Here's my solution to the flak cannon and HQ.
-100-120 munitions for flak cannon no population
-Panzer HQ cost halved but can only call in Obers and maybe jagdpIV
-Upgrade required for the other tanks which brings back the cost to standard levels in total.
-Gun can choose targets.
Finally
-AA no longer based on RNG
+1
Cost (amount and type of, cause i'm not convinced with muni for tech) can be discussed but i would like to see a half tech for T4 which unlocks JPIV and Obers earlier and having some kind of TD in case of Flak HQ destruction.
To OP and some users here:
1- Is OKW Flak HQ worst than brace. A big NOPE.
2- Is multiple Flak HQ OP? Not really. As mentioned by playercardplz (kappa), UKF has a nice offmap (in fact several offmaps) to deal with them (one of them recently nerf in order to not 1 shot it).
3- Are AFK emplacements flawed by design. BIG YES.
4- Is the OKW Flak HQ tech flawed. IMO YES.
People are really hypocrite if they consider OKW static play good and fair while they heavily critic UKF emplacement STYLE. I'm not talking about level of cancer (UK is way worst) but their basics are the same (retreat to medic HQ, sit ISG and let them afk shoot at whatever they can, protect back flank with Flak HQ, specially behind hedges).
SOLUTION:
-Not necessarily exact what Mirage said, but at least the concept.
-Bofor/Flak HQ toggle mode between AA and land targeting.
-Bofor/Flak HQ has a manual arc where they can shoot. No automatic rotation.
OKW also doesn't have any meta useable AA for teamgames.
Guess what, this applies to all factions.
Centurion/Ostwind are not cheap, M5 requires a further munition investment and (currently) AA HT are not in "popular" tech choices nor the units itself are as good.
In fact, it's easier (fuel/mp wise) to get a HT for AA, than trying to get either Ostwind/Centurion.
About AA: if toggle mode with static emplacements can be implemented, i wouldn't mind increasing range and effectiveness on them (specially if the OKW Flak is locked behind upgrade).
PD: "If we can finally buff flak bunker emplacement from OKW commanders, that would be great"
PD2: "If we can finally swap flak bunkers on base from OKW for MG bunkers and remove extra MG bunkers from USF base, that would be great"
