it's buggy as shit, and sometimes a new patch breaks everything, and sometimes you lose all your shit due to a master server glitch, and sometimes whole servers are mass killed by script kiddies.
Also none of the above has effected me, at all, and I've played almost every day for the last 2 months. :shrug:
I'm not saying I haven't experienced glitches, but nothing has killed me other than my own mistakes.
