1) Dont eliminate Fast relog
2) Implement high value of negative HPs.
My idea is, that chars could have much more negative hitpoints. I.e. minus 150. So after your char is disabled (0 and less of HPs), you are not simply quit that char, because you still have chance to recover from negative HPs state: autoheal, your mate could heal you. So simply, even you are disabled, you are still focused on current char.
I understand, that it would affect PvP style of combats. Because priority would be to disable enemy team, not kill player by player, but it could bring more tactics into PvP.
possibilities:
3) Higher level char, more negative HPs.
What do you think?
