AW is a bloody eyesore. The only time you use this is when your character is strong enough to swap out an otherwise required item for a build for the AW in order to keep up with speedfarming for key or doing bounties.
If they just fixed the spell itself, i.o.w. able to stack (to 3 like Dash from the Monk) and smaller cooldown and this thing could and should be outright removed from the game.
I don’t see much of a solution because as you pointed out we have almost no skills that affact movement and the few that do often clash with the build you’re running. That would mean you’d have to slap them on more skills but it looks silly for instance to put 20% movement on for instance Hydra. Or you have to tack them to a set, but it also feels wrong to give every Wizard set movement speed, but that’s just my feeling.
I see also nothing in a set based for movement speed. It would be a gimmick at best as it wouldn’t solve the problem where you’re pushing. And an item is what we have, but it’s not the way to fix the problem. You’d need a god tier item in order for people to equip it over the item that’s BIS now. Let them just fix the damn spell.
Honestly, I’d rather wish there wasn’t any movement speed in the game even if was at the expense of teleport.
