For me, it’s rogues. Ug.
It’s bizarre because I adore rogues, thieves, and especially stealth archers in single-player roleplaying games. There’s never been an Elder Scrolls game with a roman numeral after it that I didn’t beat and play most thoroughly on a thief first!
But man, in MMORPGs, rogues just tick all the wrong boxes. I hate stealthing mechanics in MMORPGs. I hate being slow. I hate positional melee. Actual thievery is usually reduced to tedium (games like Ultima Online and Elder Scrolls Online being notable exceptions). I just don’t have the patience for rogues in the MMORPG space, and when I look across my accounts for games where I’ve played lots of alts — City of Heroes, both Guild Wars games, even World of Warcraft — rogues, assassins, stalkers, and thieves are always the ones I never bothered to level past noobness.
How about you? Is there an MMORPG class type you can’t stand playing?
