Socializing are the most important thing in every MMO games. Some people are good and friendly, others - really annoying one. You have powerful "ignore" spell to avoid their.
Well, I re-read your first post but did not believe you. I played about more dozen mmorpg, and mainly cases when person hated other peoples, it's only one way has to solution - the really reason in its person, not the others people.
I played swtor from beta and always need to find people to party, and calling out for half-hour or even hour sometimes. So-called "ninja-inviting" was about half-dozen times - and always it was a missclicking or misunderstood by similar quest-naming. I had use ignore people only one time for annoying reapitable ninja-looting from one player, who ask no one on the questions and continue.
The key for the good multyplayer's gameplay are simple - be friendly, never lazy to ask another time other people (swtor text log full of useless thrash), help others, never be silent, and ever hope the any other person are doing same.
I've never understand that topics. You have all that you needed tools in this game to avoid from person you wan't played with, but you typed so many posts, for what?
ps. I see the greater part of people in the SWtOR prefer solo-questing and it's no good for game and community and the future to both of it. I see the some people even blame the other players who want to grouped with others in mmorpg or asked that he/she done it solo - it's so ridiculous and strange - I had better to finish my post and seek normal friendly cooperative players in the game. Excuse me, but I think that this topic are totally useless.
