I honestly think this will be what's next. Called "Warden" with a lot of CC that says "Get outta my forest." We already got a healing spec with a healing weapon, then we got a bruiser spec with a damage weapon, I think tank/CC is next. And its most unique. Hammer would be awesome (and could totally be tank CC too), rifle may happen too, but it seems to me that they like to add new kinds of playstyles, and I feel like the hammer would be too similar to our GS (a tanky direct damage 2h melee), and shield would synergize well with sword, methinks, maybe axe too for a ranged condi tank. But when it comes down to it, there's no reason. I just got a feelin. =)
