I really like Warrior for it's general look and design wise. (I like me some big axes and berserkers, only thing i like better is edgy knights and holy knights)

I don't think I agree with warrior being "simple axe healer tank" I'd like warrior to have some more complexity but also be generally comfy to play, Upheavel I'm pretty sure used to be gauge spender, while this wasn't anything complex it gave you more then the "FELL CLEAVE" gauge, which made it more interesting, I don't think warrior needs to be Paladin levels of complexity but it should have some optimisation, but still be easy to play on a basic level

Talking about Dark Knight as its basically busy warrior right now, I'd generally like a total rework of Dark Knight so it feels unique seriously if you look at how dark knight and warrior play it's practically the same if you're ignoring OGCD's
