My biggest issue of the faction is how heavily it relies on the sniper in the early-mid game and even the late game against USF and Brits.
They're mediocre without the sniper unless you're on a very favorable map and then there's 'Not Fun to Fight' when they do field the sniper but it's a necessary evil to effectively bleed the enemy. It's kind of their only way to push against entrenched infantry early on without mortars as Grenadiers are too fragile to charge/assault ground while the rest of the army is made up of support weapons.
Without a sniper, you really need your opponent to make mistakes rather then frustrating them with snipers to the point where they do make mistakes trying to kill the sniper.
Agreed, problem here is if you buff gren, you'll break the fragile balance with the support weapon and sniper combo.
I know I'm statswise not better, but I lose as OKW because of other reasons. As OKW I lose because I made obvious mistakes, lose squads or bad micro.
As Ostheer I'm really microing like a SC II player but you get so little reward and so much punishment for small mistakes.
This is also what I experienced. I tend to start with MG -> Sniper -> Grens. The sniper reduces OH capping power drastically while you need to cap with your MG (which has a bugged cap order) and the Pio which loses all fights but against Engineers.
The micro amount of the Ostheer early game is insane. If you lose your sniper before minute 5, you can simply leave because you cannot compensate that loss without hoping that your enemy does a stupid mistake.
here is maybe the issue, sniper 3rd unit is a call to light armor counter. If I see a sniper as USF that early = or I manage to conceal it and avoid bleed = keep going T2 or T1 AAHT or he micro it well (or has rngjesus on his side) and I go T1 M20 and manage a good flank and pray rngjesus to stay out of the fight.
So why don't you build 2xHMG to cover your fuel/cutoff/munition, 222/pak as support and then instead of your first pzgren build a sniper. It is much safer and you have more room to micro it and bleed your opponent.
Hell, at this level, you can go 3xPio+2xHMG to keep your ground, fast T2, fast 2x222 and pzgren. It works well vs majority of players with little micro requirement.
