Who cares how they play in the game, what other faction has undead hookers?!
I think a lot of the negative view of the ressers comes from players that were around for the book 1 era. When it was just book 1 stuff they were the worst faction and that view has just stuck. With the introduction of things like night terrors, rogue necro and dead rider, they are now on a par and can be truly horrific to play against. And not to forget the awesome henchman power of Molly (ok, admitedly not every addition was awesome!).
