Well, if by "people that knows more" you mean people that can at least type a correct sentence, then you're obviously not one of those people.
As for the haters, I don't see what the problem is. I play trooper - vanguard and I realize the Republic is underpowered, and there are class imbalances, as well as PvP problems in general, but but the game is still young, and other MMO's have had the same problems, but many got fixed in time. They'll get to ironing out the bugs, if you give them a chance to work on it, but for now don't let small things ruin the whole game for you. So get the sand out of your underwear and give patience a chance. If the game is still messed up months from now, I'll admit I was wrong, but somehow, I think Bioware is competent enough that it'll fix the problems this game has.
