I think the Warrior's Combat Animations would fit well for Hammers

There are some hammers ( most recently the Savage weapon ), but yeah.
The Savage weapon really shows how cool hammers can be tho, it's one of my favorite WAR weapons in the game.

I wish they had a bit more variety like they used to, for example BLM also had scepters and could use shields.
I wish we could at least glam them, there's actually some I'd consider using for glam but you can't because BLM only use staves now.
But yeah, It's unfortunate that they dropped this.
They played around with the idea of armor that took up multiple gear slots too I can kinda understand dropping that but ARR actually had some cool stuff in this regard that they abandoned.

Lot of stuff like that in ARR makes me wonder why they stopped being experimental afterwards, that is something I miss sorely.
