Would be great. But to have an automated system that can distinguish “players who simply are waiting” from abusers - some kind of AI is needed, otherwise ether “won’t work at all” or too many false punishments. And realistically, it won’t happen in WoW. Only manual by support/GM staff.
Would be fun!
I don’t think it’s about rewards. Right now when killed player’s pride might be hurt and they lose some time on a spirit-healer run. That’s it. But it’s already enough to make players abuse.
I had similar ideas a way back
But I think it could have quite major technical difficulties. There is already lag when players phasing in/out, so additional checks of every player on top of already lagging sharding - could be bad.
