I know it's kindof stupid but sometimes the person who gets the killing blow is the most important. Sometimes people will get away if it wasn't for that persons killing blow. Now i understand that people like UB who can be doing spit damage ooze and their auto attack all at once hitting someone is kindof unfair because they are more likely to get the last blow but this is one of the best ways to do it.

I also don't agree with the gold giving too. 4 people kill one person which isn't that hard. They get 2.5k gold all together. Than later 1 person kills another ALONE and he gets 1k gold. How is this fair. Obviously the person who killed the other person alone had more skill involved yet the four people gain more money.

Main reason they did this is because it would be too hard to code in another way and this way works fine as it is.

Actually, you are quite wrong; what the op proposed would be difficult (not impossible) to code as their are a ton of factors to consider about distributing money using that method.  For example, imagine someone who is in an extremely long fight (say 5 minutes), and during that time they were healed, shielded, used potions, attacked by towers, attacked by creeps, attacked by enemy DGs, etc, keeping track of all that data to split the money would be very intensive.  I believe the current method was used for multiple reasons, one of which was probably simplicity. 

An alternative method for handling death, would be to penalize the person who died by imposing a gold and exp debt (based upon level).  This alternative method would solve the 'feeding' problem, and keep games on a more competitive level despite a few deaths occuring on one side.  I think this method was overlooked because it imposes a penalty and not an obvious reward, but I think it makes much more sense given the mechanics of the game.

This is actually a interesting way to improve the gameplay. When people gang up to get you (push, caplock flags, get towers, whatever) you have to retreat if you are alone, unless you want to gang up yourself. When all the DG on one side gang up to hunt DG together, they can use stuns and slows to hunt then down, and if they get additional money for this, it doesn't seem right. If anything, teaming up should be penalized.

No fancy division is needed however, killing blow and assist is fine, but it ought to be shared (no bonus), and so should xp. Killing blow should get like 60%, all assist should share the other 40%.

Yeah, it does seem ridiculous the amount of gold that can be earned on a single kill on assists alone. It doesn't make sense how you can have 4 solo kills, and be awarded less gold overall than a team who gets 2 kills but were trample kills that everyone got a piece of, even if it's only a tiny amount of damage from each.

I'm for the % of damage dealt method + a reasonable gold bonus for whomever got the killing blow.

I agree that people like Regulas get to exploit this the most. Can be fighting on the other side of the map. Pop one snipe on a guy in a 1v1 and go back to farming. Then the guy who got sniped dies, free 600 or so gold for Reg for the "Assist". Its just like if he snipes everyone who gets in a fight he always gets money. I've done this before... and ended up at war-rank 8 with 12k gold. Bought straight to catapultasari... gg thanks for playing.

Edit: Also its just the fact that getting the assist gives you free money, and doesn't take it from anyone. I'm not sure if its a bad thing or not though. Like its a game mechanic that everyone knows and should exploit. Hmmm...

Teamwork is already rewarding enough. The more people you have fighting against a demigod, the higher the chances of killing them, which means they will be dead for ~30 seconds (and away from the lane for longer than that) and not get any experience or gold from their mines, while you continue to do so.

There is no need to give people such huge rewards for minimal contributions.

What about the Sedna who healed the team mate at the last minute but dealt no damage to the enemy for that fight? Or the Queen of Thorns who rushed in to throw the shield up on you just in time, completely turning the tables around? Surely such assistance deserves reward, no?

How would more support oriented Demigods stay in the game if they're losing out on gold reward because they assisted more than actual killing?

Typically the assist demigods are so geared towards optimizing the citadel / teleport scrolls and cap locks that losing out on 1 k gold every time a kill happens is not the biggest problem in the game. In 2 evenly matched games, the support a support oriented class provides there team may not pay them off in gold, but it will most certainly pay itself off by allowing the team to win.

This reduces the fun factor of support classes, but even with the assist system in play this same effect is seen. Rarely does QoT get a killing blow. But her skillset allows her to stay on the front lines without spending TONS of money on gear, which when she manages to earn more money she can invest in the citadel and thus further the teams efforts. Assassin DG and DG builds that are oriented for 1 specific task must spend more gold achieving that task, its the support players role to help them get there.

I don't play QoT so I can't comment on her, but I don't see this division you talk about. Am I supposed to max heal and buy upgrades if I play Sedna, or what do you mean with "support DGs? If I play a farmer like TB I can get the upgrades much more easy.

You need to work on your reading comprehension. The last line in the OP:

"There can also be bonuses based on defensive spells/buffs and offensive debuffs, which contribute to the killing."

Well I think that he should get more money. Not 15.000, that is just way too much. But still, a lot of gold. I mean hammering at someone for 15.000 damage? Well, you really did earn buckets'o'money. Of course, as a previous reply said somewhere ( too lazy to look for it ) that will get refreshed every 10 seconds that your target is not hit by you.

That way, if you keep hitting an opponent the entire game, but he keeps getting healed and runs away you won't be getting something like 100.000 gold when you finnaly get to own him. Although I would love to have that much cash......still, it's a tad bit much for a fair game .

Also, maybe if some sort of revenge mechanism is implemented so that you get more gold when you kill someone that has been killing you. And the announcer will say "REVENGE" very enthusiastically, although I really don't think he can top his tone of voice when he says "The forces of light have constructed a FINGER OF GOD !!!!!!!1111oneoneone".
