Ok, point taken...kinda. You know how the adage goes: "sometimes a good defense is a good offense?" assassins & other classes have abilities & other cards to make up for that. Assassin has an ongoing ambush card for the entire ally pool...I mean that makes up for a lot. He does have mugged (-3 to opposing hero, +2 health), golden katar (perpetual defense)...you see where I'm coming from?
Yes they're a bit more soft as targets, but though cliche, they're really damn tricky...and that's assassins. I could go into the other classes, but I think I made my point...and wulven oh EM gee...I don't even wanna go there w/darkclaw. His mess NEEDS to get nerfed, just like Others got nerfed. I've always hated wulven decks from the start. The whole regeneration theme got on (and still gets on) my nerves.
