What ticks me off is when they kill ALL of them, and I am not even a BLM, or any AoE, I just think it's fun killing an army of mobs by myself =P
I was RDM, and I am going around Diaing everything in sight, and linking other mobs, then these two people run up and start killing off everything I was like "Stop killing them please..." about 5 times, and they just KEPT killing!!! ARGH!!!
Personally I train farm for getting the boredum out of farming. Killing one mob, sheathing, running to the next, kill it, sheath, run over to another, IS JUST SO BORING
Taking off one if your a low level and need the experience, fine go ahead, but if your lvl50++++++ and you slay all my mobs, You are NOT cool!
I see trains all the time, I don't even take off one, I don't care if they train farm in the area I am leveling, he pays 12.95 too, I pay, but am I going to get overly pissed off because he just farming? Of course not, people get too pissed off for the littlest things!
