OKW:
Increase raketen crew RA by 20%. It's too resistant to small arms after the 5man upgrade. Explosive dmg is the only way to kill it right now which makes them very difficult to decrew. The rak was given a double buff to survivability as +5 range is a defensive buff as much as it is an offensive one and extra man is self explanatory. The 4man rak suffered from being one shotted by explosive damage. Increased crew RA will not impact survival against explosive, however, it will largely negate the increased survivability vs small arms which is likely NOT intended and hence a side effect of decreasing the chance of being one-shotted.
+1 the rak feels a little bit too durable atm. Overall i think most okw units are in a good spot(vet0). But there are 2 things that could be adjusted: The teching and the veterancy.
Problems i have with the okw veterancy:
a; Volksgrens
They scale fast but their vet 5 combat power is quite bad compared to riflemen, sections and even cons. Their vet 4 (+7 sight in cover) is pretty worthless. If we swap the vet 5 healing to vet4 and remove the sight bonus, we can give them an adequate vet 5 combat bonus (nothing major, 40% acc bonus like other inf and maybe target size to 0,70) so they can compete in the late game.
b; Obers
Nothing major, but if their timing stays the same, they could benefit from a reduced dmg veterancy like grens. So they get a little nerf vs small arms fire and on the other hand more durable vs rocket arty and tanks. Seems reasonable for a t4 unit, who has zero at capabilities.
c; Panther
The vet 2 armor bonus is mediocre. The armor goes from 260 to 286. The chance for a jackson at far range to penetrate a vet 0 and vet2 panther goes from 85% to 77%. That makes a panther around 10% more durable. Meh. Imo either buff it to 15/20% or just remove it and replace it with something like moving acc or +40 dmg.
d; Flak HT
I think the unit needs a hp buff from veterancy (like 222 or M15A1 AA Half-track), maybe remove the vet 3 or vet4 boni for that.
e; 7.5cm le.IG 18 Infantry Support Gun
Swap vet4/5 with vet 2. Getting two smoke range buffs in a row feels bad. The vet 2 unit performs like a freshly built vet 0.
f; Tiger B 'Königstiger'
Getting the reload bonus at vet 5 is too late. Just move it to vet 3 and give the kt something other at vet 5 (like churchills self repair).
With these changes Battlegroup would get some nice buffs, obers would be more viable, and Okw overall would scale a little bit better into the late game.
