Actually yes, I really think I deserve the gold. Regulus didn't do 95% of the damage.
Okay, if in stubborn stupidity you tell regulus not to take the kill, then guess what happens: He gets away.
See, the game isn't about blowing every cool down you have right away like an ADD crack addict. All this does is drop your best cards and give them every reason to kill you, or run. It's a game of mathematics and mind-play. You lull your opponent into thinking he has an advantage, and you only chip away at his life enough where your cooldowns complete the kill.
Honestly, if one of your teammates is wasting mana and blowing cooldowns just trying to get last hits, then thats their fault, and they aren't contributing anything to the team. My recommendation would be to find better teammates, not change the mechanics of the game. You also however forget to neglect that sometimes, it's GOOD to allow a teammate to get all of the last hits. All of the gold funnels to him, and he can for example buy upgrades, while you use the assist gold to buy items. Theres a-lot of room for teamwork in the current system, and I can sympathize with having to deal with shitty pugs.
Towers, creeps, AoE that was not even meant to kill my target. The target whom I had no trouble killing otherwise.
