Try using Guards if you think PGs are weak infantry based AT.
Guards are Guardbage (hehe), I agree.
And would lead to OKW v2. Pgrens are just fine if you take steps to mitigate their fragility. Putting them in buildings, Screening for them etc. What they are NOT as Volks blobs that just run headlong into massive HE rounds and AI units to finish off armor with absolutely no drawback at all.
If Pgrens magically were able to do this then DAMN right Ostheer would have more options. Similarly if Zook blobs were as effective as OKW shrek blobs then USF would have alot more options.
But those options wouldnt be fun...
Putting them in a building is actually a horrible idea as then you cannot instruct them at what to shoot at, and screening is pointless when a single HE round or a shell from a Scott can instantly wipe them with no warning.
And if you are blobbing volks, as in grouping them up and running around your just asking to get 6 squads wiped by a single HE shell.
Pgrens shouldn't be able to magically survive HE, but they should be able to not get instantly wiped extremely easily. And considering how expensive they are even if you did buff Pgrens survivability they would never be able to be blobbed. With Ostheers huge MP drain.
Between PAKs, P4s, tellers, and fausts, the Ostheer have plenty of ways to deal with enemy tanks in 1v1. I pretty much never upgrade my Pgrens with shrecks. I like their AI much more. In team games, Elephants are fully viable with a teammate being able to cover your weaknesses in mobility. Don't mess with an Elephant.
I do enjoy Pgren's AI capabilities especially against Rifle blobs, but the P4 is a very poor investment as far as AT goes. It can have it's round bounce pretty regularly against Shermans and T34's.
