Yeah.
Oh. Ow. Yeah, you're definitely a low-op group (or you don't get any WBL to speak of).
Optimizing just means making decisions that make you better at what you do and the game more fun for you. If you find making a useful and fun character distasteful, I kind of feel sorry for you, honestly. Having fun is important to you as a player, and being useful means you're not a drag on the group (and you, as a player, are never stuck twiddling your tumbs for long periods of time in-game, as I can't imagine that's fun, either).
