I sadly cannot play the mode as I am away from my pc, however I have a few tanks that I theorize would benefit a lot from the buffs in this mode.

Obj 274a: usually it suffers from bad terrain resistances, bad engine power, and bad dispersion. The mode helps with 2 of these and I already run grousers on it, it would turn into an incredibly speedy medium with the 58km/h top speed (which it usually struggles to reach). It will also hit like a truck, this time without the chance of rng screwing you over.

Ambt: similar story: bad gun handling, and kinda slow, but the 1080 damage clip would be absolutely devastating if you can deliver it consistently, sadly it won't help you with the bad reload time.

Caliban: same as ambt pretty much, but with a twist that its hesh would become useful. Think about it, ap is mostly used because it has mad penetration, and it's a struggle to even hit anything in this tank, but now you could even hit weak spots and lower plates consistently, and thus 180 pen should be enough for that

Gsor 1008: yet another devastating clip that could be delivered consistently, and the engine power boost would make it play more like a support medium tank.

Cobra: I'm repeated myself enough times by now.
