As the hover problem is getting worse by the day, something that needs to be pointed out. in combat red hovers are pretty balanced and are an alt to omni and meat grinders in their use a good medium speed class mobility option which trades something for its advanced mobility.
The problem is blue hovers which have the plus sides of everything but none of the down sides. And to fix this there is one quick nerf that would work.
Hover nerf: blue hovers only (red ones get it as a perk.)
Removes their stability bonus, they no longer self right and must be flipped by an ally like any other build their hovers turnning off if upside down.
