[Ultimative]

The damage from the Shredder doesn't stack, like how fungals work.

I don't really see how they can make it work. It's a nice idea and kind of an interesting unit with its little no friendly fire gimmick, but it seems to me there are eventually going to be some maps which it's almost impossible to play vT on because of how much map control the Shredder would give in its current state.

Tbh though there's probably not much point in thinking about it, Blizz will likely cut/redesign a lot of this stuff anyway.

Just leave the Tempest as is ;p
