Even these forums are not nearly as bad as that OTHER game's forums.
Surprisingly I don't see rudeness in game much, although I play off hours except for raid nights, so my exposure is probably quite limited compared to most.
The drama from this 1.6 patch however, prompted me to go mmo shopping today, and after reading the first couple pages of a few other mmo general forums (STO, TSW, & WOW), it's evident that there is a level of anger present here that dwarfs anything I saw glancing at the other mmo forums.
I think alot of people are disappointed in the way this game has evolved and are taking it out on each other. Maybe the other games clean up the threads and posts better? I don't know. It is sad though.
