Hmm... So many cool weapons I'd love to tank with!

Naginata:


Glaives:


GUNFISTS:


Heck, I could even see some sort of Magitek Grenadier style class, where you use a similar device as the MCH does but you generate a bunch of grenades and other explosives and toss them at your enemy, with a feeling not too dissimilar from the Saboteur soul in Rift, tossing out different bombs to stick onto a target and then detonating them all at once! - The actual weapon model could be either some sort of Magitek-esk Grenade Launcher or even just some sort of Grenade belt (Either around the waist or across the torso)
