Hulk’s loki slam ability while in world breaker form should just be a regular ability on a long cooldown.
It doesn’t fit with it where it is now in my opinion. Because when your ult-ing, you only have ten seconds to knock around enemies and do damage. You don’t want to waste that time with a super long animation that doesn’t really do much damage.
I would just move it to his regular kit and give a long cooldown, kinda like Dr. Strange’s portal. It would give him more options to work with than what he currently has. It would also make him more fun to play. His kit is mainly only attractive to the highest tier players, while most casual players find Hulk’s kit to be stale and weak.
