I cancelled my sub a week and a half ago due to RMT, bots, toxic yells, lack of content yells and mercs/cheats, that and not being able to ignore /blist them (due to the 100 cap).
I'll dabble in and out of the forums and news, to see if any action is taken and if it isn't - I won't return.
Ten or so people I know have quit over the last month due to the above reasons.
