Aggro needs fixing

I can attack something and use up a few of my abilities only to have it run away just before I kill it. This happens 99% of the time when bots are around. When the target runs away it becomes invincible and regenerates back to full health. It becomes a huge waste of time.

I would have put this in the bug reports but someone would claim that it’s working as intended. That would be true if someone else had taken the aggro first. This happens after I have started attacking and I watch a bot teleport through. Something about it causes the aggro to reset and target the bot instead.
