Sorry to say but I tried guild wars and city of heros but neather of them were as good as wow playability wise.
both these games have stupid drawbacks such as if you die you ether lose exp or your toon becomes weaker the more you die so you have to sit around for hours wating for the debuff to ware off.
City of heros/villans other then the EXP drawback drim dieing is an ok game.
I have not tried this one but iv been told Lord of the rings MMO is pretty decent though i dont know the drawbacks , if there are and, to the game
right now WoW playability wise is still the Best MMO out there and not all the people on wow are mean it just depends on the server you are on and wether or not you can actually find a decent guild so that you can actually get into raids and what not.
i dont know the situation of where people were mean to you. but if it was due to say your gear yes people can sound mean but when it comes to raids they do look for well geared people and people who know their class so if you were not quite up to par then people can get a little testy.
you could always wait for a while until the Star Wars MMO comes out and play that though its probably going to be another year before it does at the very least.
