I'm curious as to how a "tanking class that uses two-handed weapons" is going to work out. I see it as better for DPS, obviously, which given the current game mechanics would make it excel at 5-man groups when equipped with better gear (right now tanks need to downgrade their tank gear when go back to 5-mans so they can keep up with aggro generation, especially when survivability isn't all that important).
Agreeing with the former Admiral, they must have some kind of new mechanic using the runes that will increase their avoidance. Somehow I doubt "Death Rune of the Monkey" is going to be the name, but it might be something similar that simply adds a set amount of dodge.
Seeing as there are (three?) rune types, they might have it be something like the forms of the Shivaan Assassin; ice will be the tanking, with some snares and mitigation, shadow is the recovery, and fire is the cleansing/DPS form. If that happens, then using a combination of frost/shadow (death?) runes will be for the tanking form.
Basically, we have no idea, but it's fun to post in a new forum :)
