When are people going to learn that a MMO is about fun. How one achieves that fun is up to them. Saying that it is about roleplaying is just ignoring the whole actuality of the game. The reason we base our opinions on damage output is becaue that is how you achieve almost every quest. Outside of mastermind which you still need damage to get too adn the other puzzles in the game, There is a boss that has to be defeated. If they require you to sneak around him and he then is foiled in his nefarious plan then great, then sneak would maybe over powered. (personally think that is a horrible example)
Thats a fine plan on how to play a character but I think you are in a small minority of players who attempt to gimp themselves in order to find enjoyment. In fact I would wager to say that most people like playing powerful characters to emulate a godlike psychological fantasy. But I will not bust out with my too many years of psych classes. The older MMOs where exactly that older, this is a newer one and there fore is subject to the growing genre. I can't count the number of people I know who play just because the combat system is unique.
Yes every class does need something to be good at. That is why I have advocated the benefits for pure class builds. I understand that you are having fun and balance is not an issue to you but why post to say so. Are you against balance and what super inflated spells mobs and damage? Do you want over powered items and god like stats? I think you jsut said you don't.
