Reminds me a bit of Kalise's
Viking:
On the point of both I think a two-handed melee weapon that isn't bladed is about time :3.
Could be neat to capture some of the lumbering destroyer archetype- perhaps mixed in with that sudden burst of hulk speed as part of the burst concept you've both put forward ("oh yeah big and scary but very slo-- OMG WHY IS IT MOVING SO FAST, WE'RE SO DOOMED"). lol :).
Some imagery of that reminds me of Crusader / Diablo 3 (slow-ish but has a few skills that then bring it in like an angry holy wrecking ball).
