Oh... another one:
Yesterday, I was helping a lower level player kill hogger. (I needed him too but I was much higher than the quest so I like to say I was helping, lol.)
Anyway, so we are killing him and hes taking good chucks out of my life but nothing I cant live through... then this other group rolls up waiting for him as well, but there are too many of them to join our group.. so instead of waiting for the spawn again what do they do? They get the mage to spam sheep hogger to gain his health back. They were trying to kill me so they could tag him after he reset. Ridiculous.
Luckily we still killed him and that other group had to wait. I felt great. LOL
