Bristleback (without Bristle it’s just back)

Storm spirit. A mobility dependent hero. With zero mobility.

I’m also curious on the reverse, as in, which hero would be LEAST affected by their ulti being gone.

A lot of carry heroes come to mind, and maybe CM?

Zues, can’t steal kills from across the map

Hoodwink

Ehm Slark? Drow at least has silence and slows lmao

Bounty hunter?

There’s a lot of heroes in Dota that rely so heavily on their ults that they can’t really do much without them. Invokers a good one but I think you could do some shenanigans with items to make him into a sort of A-clicker whereas Meepo is just . . . . I mean look at him.

I don’t agree with Drow. Her ult get easily disabled anyways but you can still build damage items to her and aghs for her 1st and 3rd skill!
