The respawn location and the lack of a timer if youre killed by pvp.
If youre solo or duo roaming in the upper districts like temple or arboretum. You see an opposing faction group of 5 people. You decide to not engage them, because even if you can kill them, they will respawn one by one before they are all dead and it becomes a neverending fight that you will eventually loose due to resources etc. If you see just one player, no problem, you can kill him and be gone by the time he respawns and returns.
If youre solo and see two people( A and B ), when you have killed A and while you are killing B, A is already returned and ready to take revenge while you are still fighting B.
Hope that was understandable as english isnt my first language. Please
@ZOS_GinaBruno forward this to the IC team.
