In other games (WoW included) because of the broker and market systems, its very easy to be a complete and total jerk and douche bag and still be able to succeed in the game, and because such behavior is tolerated and sometimes even encouraged by other MMO's, the community was rather, well, leaving something to be desired. Games like L2 that have a karma system rather than all out pvp encourage players to behave, and games like ENB that rely on people selling to others in auction channels, with no way to trade gear to your alts, no mail system,ect. force people to be nice or get ignored and black listed.
That doesn't mean games like ENB and L2 are without jerks, it just means it's more difficult for the jerks to hit max level and have what they call "fun"...most of those people were weeded out of ENB early on. However, I still remember plenty of people who were max level and kill stealers and jerks.
I have a piece of advise to both sides here. Deal with it. ENB is a computer game. Try to have fun, and if it is impossible for you to have fun in a MMO because someone pissed you off, then go find another hobby...because it WILL happen again. That is part of MMO's...the whole Massively Multi-player thing...
