yes, ost repair is pretty weak.
Difference with the churchill is that the churhill has higher healthpool and has access to doctrinal crew repair abilities. 5 man Sappers also repair faster than Minesweeper Pios.
I didn't make an argument about what the Stupa is. I didn't even say it was weak. Rather I asked what the percieved notion is and how you would improve it since the balance team feels the unit is weak and have now chosen to buff it.
I'd like the range to stay where it is, but I also would like the unit to be more reliable due to lack of turret.
Let's not go down the doctrinal rabbit hole because then you have stuff like Ost pixie dust on every vehicle adding to survivability.
I think brum is in a weird spot because it still has vet focused around short range (armor buff) and also simultaneously bunker buster that lets it clear units at range.
If you ask me one or the other could get removed, adjust the vehicle into a specialist for either role with focused buffs.
Issue with the old brum was just destroying everything at range and then even if you closed with something like an upgunned Sherman he would be bouncing all day with vet 2 armor. The very definition of frustrating gameplay.
