I can't wait for 1vs1 games Tiger Ace instant repair on the field simply by equiping sweeper.
Teamgames are already broken because of OKW being able to fast repair Ostheer tanks. OKW repair speed bonus should have been nerfed the moment resource restriction was gone. Relic now decides to only make it as an upgrade is the minimum move.
That TA 1v1 meta, especially with buffed allied TDs on balance mod surely will make TA so much more dangerous

Pair of pios/CEs do a fine job at vet2, thing is, getting there is extremely challenging if you don't go for flamers every time.
- Ostheer is a faction that can field stock panther/brumbar + whatever special heavy/super heavy unit it wants and not to mention their tanks gain armor with vet.
- Soviet doesn't have stock heavy tanks and doesn't get armor with vet. Not having stock heavy is probably why you don't feel the need to have faster repair speed. Your tank have less HP pool to repair.
These two suffer the same and I'm not talking about making pios and CEs rep speeds match vet2 sweeper spios, but either improvement with sweeper or ability for sweeper to actually get to vet2 for the bonus.
Needing 3-4 squads to effectively repair what other factions do with single one isn't exactly balanced in my book.
- USF, again, what is the heaviest HP pool to repair? 800? And you are asking why paper tanks faction has better repair speed?
And for USF I wouldn't change anything, they don't have heavy armor(is panther heavy tank? no? then pershing isn't either).
- UKF: Don't have the faction, I have no idea if the repair speed bonus is ok or not. If not, adjust it, not Ostheer one.
Think of ost, but with more expensive everything that isn't med tank and teching, they still got excellent repairs, both stock and doctrinal ones.
