Puma up? Seriously? That thing wrecks allied stock mediums unless you play it wrong. It has good survivability since it has smoke. And quityerbitchin about pen rates. Try Jacksons vs heavies and then we might talk. Puma out ranges everything that isn't a td. To quote many better men than me "L2P issue."
I still fail to grasp how okw would fall apart if shreks were moved to sturms. You'd get a snare and ai upgrade for volks and everybody always has 2 sturms by mid anyway. You'd have 4 shreks still, where is the problem? Also your raketenwerfer would get buffed too. This would add a bit of depth to the faction, not cripple it.
God forbid you can't get the best at weapon on your cheap nigh invincible infantry.
No one is saying the Puma as a unit sucks, it doesn't. But there is a difference between saying it's bad and it's not worth the fuel. You would be better getting a Puma then say, spamming flak traks if your intent is to counter light armor. But generally your better off saving fuel for a Schwer or using your early game fuel to get a Flak trak if you need to counter infantry/scout cars or a Stuka if you need to counter weapons team spam. This of course assumes you went Mechanized. If you went battlegroup it doesn't matter because no one in there right mind is going to go BG -> Mechanized unless you have a team make backing you up.
The issue people have is that giving shreks to sturms would basically make them Pgren's 2.0 which is boring. And making Volks grens 2.0 by giving them AI and Snare is boring.
Hey here is this faction that does alright for itself, lets make it's early game model literally the worst faction's in the game.
