You're going to have to tell me what the core issues are then. I thought I dealt with most of them.
I don't think the four-man Panzer Grenadier squads are overpowered to be honest. In combat, they're the same as Wehr Grenadiers right now, but are more expensive, have weaker guns, cost more to reinforce, and can't throw grenades without an upgrade. Pretty sure that Riflespam > PGren spam, which is how I wanted it to be.
Not saying I'm right and you're wrong, but I need more details.
Well, if you couldn't figure out the core issues with PE you shouldn't have started in the first place to be honest.
The problem from pgrens isnt the squad size earlygame, the gren hitpoints + soldier armour is a problem. With their low hitpoints they get critted by flamethrowers too easily, and cost too much to replace in case of losses.
To fix this issue, all you need to do is to modify the hitpoints from pgrens and tweak the reinforcing costs. There's no need to put in 4men squads by default. This creates more issues than it actually helps. g43 4men squads massacre Riflemen, even with bars.
By removing shared vet from PE you nerf PE blobbing power while not giving them something to compensate. You're not adressing the core issue, you're just fixing a symptom.
PE lacks blob control weapons (real artillery/supression), which leads to PE having to blob against allied factions to match them in firepower. As you cannot supress properly you need firepower to avoid getting rolled over by allies.
These are 2 points only so far. I could go on with every other small issue, but I doubt it's worth the effort since I'd need to spend 2 hours writing everything up. Reason seen below:
So maybe a list of the core issues would be a first step then.
To quote an earlier post from myself, thanks for reading carefully
PE has several flaws, which are:
1) paper armour on vehicles, which result in most units having a very tight window in which they can be useful. Afterwards they're a waste of resource to build
2) blobbing bonuses
3) weakness to early tanks/light vehicles
4) Pantherspam in teamgames/getting heavy tanks without limit for manpower only
5) No real anti-blob weapons apart from sector arty/Hummel (so limited to 1 doc)
6) broken vet system (defensive vet always better than offensive vet, especially for vehicles) Shared vet isn't as bad as people make it out to be though
7) Ketten OP with hidden detection, fast movement and sdkfz22x armourtype.
ofc Pe also has strengths:
1) very early vehicles that can have a huge influence on the battlefield
2) many specialization options for infantry and vehicles
3) very fast teching
4) strong doctrinal units that can fill up holes in the own teching
5) start off with their mainline infantry
These are not even all issues, but those were the ones that I found originally. There are some more subtle issues, which are related or depending on larger problems within the faction.
