I got the roar of the north on the 1st day of Spec Ops (first time I've ever got a Spec Ops daily roulette weapon). I really, really don't see the fuss with it. I used it once or twice to see if it was that powerful, but the damage it does is just...meh. Not great by any stretch.
I'd say the best weapons that have come out of any Spec Ops thus far are the Arc Reactor and the Phoenix Pinion. But the Dark Sigil trumps them both, in my opinion, and you can get that just by farming Dr Strange's premium mission. I use Hoarfrost Mace, like you say, just for the protect ability. That Hotshot looks great, but I never got it
In other news, Deadpool has just gone off to train to level 12. That leaves me with Valkyrie, Colossus, Thing and Sif and that's every character at max level. Moving house in a day or 2 and will be without internet, so I figure by the time I'm back on there'll be new characters/costumes and whatnot. It never ends...
Oh, by the way, I just realised that I don't have anyone on this thread added as an ally in the game. If anyone wants to add me, my Facebook address is http://www.facebook.com/reganvondoom.
