With all the problems trying to get a game started and the general slowness in one starting, anywhere from 10-30minutes to get a game to start with all the connection issues and game freezing on the open games list, it seems balance is really taking a spot way down low on the list.
I've played all but Sedna so far of the Demigods. Beaten SP on Hard w/ Oak. I play Oak in Pantheon but switch up in Custom games. The easiest demigods so far have been UB and Erebus. Some basic nerfing is needed of these 2 heroes. Until then the games vs these demigods have been pretty lopsided. People are starting to learn how to cheese out these heroes the most. I realized this on day 1 when I played through them all in network vs Computers.
Erebus - Bite. The return life drain needs to be reduced by about 30-40%. It has a snare and an armor reduction with it. Doesn't need to lifetap for the full amount. Cooldown could also be increased.
- Mist. Should not remove debuffs.
Unclean Beast - Venom Spit needs to do half the damage it does. This should be another complimentary damage to his melee dps similar to what Ooze is. In its current spammable state it does WAY too much damage.
Rook - This demigod is asking for some love. His Smash needs to be a 1 second cast and the area for max dmg needs to be increased. Typically the only way you hit with this vs anyone with a brain is with a stun.
Walk speed needs to be increased and hitpoints returned for a start.
lvl 15 Poison Arrows needs to be more like a 25% chance to slow. For being such a slow walker this guy could really use some type of reliable snare.
How many games have you played? I'd also argue that Vs Computers does not count (the AI is poor and not very good).
Real games Vs real opponnets needs to be played and data needs to be gathered from more than just a handful of games.
That said I'm sure there are some balance issues, but I can't say I agree much with your assesment.
Open games imo is the slowest way to get a games, Skirmish and Patheon right now are the ways to go if you want to play a lot of games. Open games really the only advantage is if you have friends you want to play with.
Erebus
Erebus's health regen does feels very strong if you min-max it so he becomes pretty tough to take down, in beta he was so weak that you pretty much always had to use Mist form to live. Now it feels like it's hardly worth putting points in. But this is with me playing 10 games (almost exclusivly Erebus). Of course with high levels and gear I think other Demigod can pump life regen and gain as well.
To get Erebus to this point, I'm usually spending 9000+ on gear and 6000+ on allies/minions. It's not cheap and it's not till late game. I have the hardest time against a well played TB or Regulu, both of which have great range attacks and typically need to pump speed so they can out run me when I move to try to kill them.
With Batform + bite and an army of minions you can take someone down very very fast (Most gear focus on giving you and your minons buffs) but it's expensive and selfish to got to that point.
Unclean Beast
I need to play him more but so far I've found one build that works effective and it revloves around Venom Spit and movement/speed increases, so reducing that in any way I think would be a bad idea. His DOT is really a good counter to both Erebus's health regen and Sedna healing auras. Overall Unclean can't take that much damage and really has to play hit and run utilizing his venom spit.
Rook
He's a siege Demigod, that's his specialty taking down towers (defending areas with his own towers). He's suppose to be slow, he's not designed as a Demigod killer, if you want that Regulus is who you should be playing. That said I've killed plenty of Demigods with Rook. IMO his hammer slam is best used to kill creeps (and gain exp) not to kill Demigods, but if Erebus with his charm work together (or any other stun ability) it can be very effective.
Levels and Gear
But in any game if a Demigod gains levels and gold on you (I.E. you're behind) they are going to feel super powerful to the point that it does not feel balanced. But this as as designed it's what helps push the game to finishing. The trick is to not die -- retreat early from bad situations. Of course some of this is also due to the lack of player feedback, I have no idea what gear a demigod is rocking and I really wish there was a way to see it with out cluttering the UI.
Maybe if when you died it showed a window of who killed you and what gear they were wearing, that would be cool.
So you could examine not only what they gear they are using but would give you a better understanding how to min-max that same demigod for another game.
