Mostly I was speaking from what I imagine to be a game designer's point of view, not that of individuals with individual preferences. Personally I love the way thaumaturge plays. I plan to start phase 4 as an arcanist, since the way I've been roleplaying Myxie is very scholarly and bookish, but if it doesn't play the way I'd like, I'll be right back to fireballs and blizzards. My point was that having one class with twice the potential of the seven other classes is going to skew game balance to make that class more attractive, at least until other classes also have options. In general, the MMO community tends to react strongly to even slight perceptions of class imbalance. One class = one job is likely the fairest way to balance it until all eight classes have multiple job options.
