I think it may be worth considering whether or not we want to keep wear and tear as a mechanic or if we want to change it to not be so punishing for more basic repair units. This would obviously require doing something about PE repairs on all base squads, but I think it might be worth considering.
I would be cautious about this as it would massively buff heavy tanks.
I would not be. Tigers are a sub-optimal choice compared to investing the same resources in stugs or panzer4s. King Tigers are complete shit and just playing to lose. Pershings are meh and comparable, kind of, to shermans but vastly inferior to just spending the resources on a Calliope. Only the JP is actually good but that is because unlike other heavy tanks, its survivability comes from speed and armor instead of just a wall of hp. HP tanks like the KT just get knocked to half hp, take 10 minutes to repair, eating half or more of your population, then come back and die instantly because they lost a third of their HP to wear and tear. Useless. The tiger/pershing have the same problems but not as bad.
