I can admit that you can make a solid argument for the guardian class prior to 2010. But then again, aggro was just a goad away for swapping, "remember that"? lol
Anyway, it is what it is now.
I have also heard about the Germans doing well on pole arm spec etc. I can see them doing decent if they are geared the hell out in T4 with a mix of full plate and heavy gear to get more dps. But to me, it's just not worth it for the lack of defense you have at that point. Then again, maybe they like the challenge?
Regardless, SnS is solid as hell, and all tank class's "imo' are freaking easy mode nowadays. Only real class in game that takes some skill is maybe the BS and Hox. Haven't played them in a min though. And even those aren't that hard to do well on. It's just more challenging than the other class's.
