I would be okay with alot of these changes, making it more focused on team based.

Tanks would not be better DPS, but frankly there'd be fewer people playing them. They already die last in the arena anyway, and its likely if they had moral boost defense they'd rarely be attacked unless chain-ganged. Well I say that, but they still are uber stunners. I dunno', I'd have to give it some thought. But certainly acceptable way to handle morale
