my idea of Great Axe
note: i messed up on the numbers so they probably either make no sense or are ridiculously high. think of it mostly as slightly more damage than the hammer in all aspects. (without the trait)
~I agree a great-axe would be epic! The ‘Executioner Costume’ has one anyhow right? My only fear would be the facing it’s synergy with a ‘Hammer’ O.o!
+1 one great axes
But what you describe is a OP Greatsword
Great axe is pretty much guaranteed to be a usable weapon at one point, I remember someone from Anet talking about it on a stream a while back.
I would change your 3rd skill to do more damage the farther you charge, it would make a good opener and not many skills have that feature. Also, it seems you only thought of this weapon for a Warrior, which is the class least in need of a new weapon.
The professions I would see being able to use the GA is Warrior, Ranger, Engineer and maybe Guardian.

well these attacks would obviously be telegraphed. its more of a hammer minus the stuns (but hammer is getting a damage nerf)
