Assault Engineers are fine but we definitely need a MP reduction, I mean come on 280MP? I would rather build Rifles instead, maybe reduction to 240MP will suffice.
I think panther should just be 145 fuel. It was perfect price before relic changed it...
NO, just NO. There is a reason why OSTH Panther is priced as it is now. The Panther spam was an abomination before and you would see 3+ panthers every single game. I even myself in one game build 4 Panthers. I would recommend lowering tech price and that is it.
Puma is perfectly a viable unit for OKW. The range, speed and damage is more than enough for the Puma, just support it with Volks with shreks. Puma is NOT under performing, this unit rewards micro SKILLS and its not a KT with A-move ability.
On the topic, OKW will be far better off with if they have a squad with double shreks than Volks. PGs with double shreks supported by armor (AT gun) just devastate medium armor.
