There are good MMO classes and bad classes. There are well-designed ones and ones that just never gelled. But every once in a while, you come across a class that clicks on every level and works so well that it goes right to the top of your favorites.
Among the many MMOs I’ve played over the years, only a small handful of classes in these games had that effect on me. City of Heroes’ (well, City of Villains’) Mastermind was one of these, cementing itself as the best pet class I’ve ever tried. And I’ve always been somewhat in awe of Lord of the Rings Online’s Captain, who really nailed a great hybrid build while remaining thematically distinct.
What would you say is the best-designed MMO class you’ve ever played? What about that class put it heads and shoulders above the rest?
