I'm not sure if there is a need to modify so much the emplacement system. I wonder what would do, for instance, if we simply forbid repairing them while braced.
The bofors could also use a reduced vision (by half) so it need spotter to work properly. No more brain dead VP/cutoff/fuel point guard on so many maps.
If the comet remains that strong, why not simply limit them to 1 per player. UKF players already have access to the FFs, Cromwells and Churchill variants with doctrines.
I'm not sure if it is a bug so I won't put it on the COh2 Bugs section but the reason why your ambulance can teamkill is because around the USF base there are barrels that can be crushed if you drive close to it.
Crushing them will count as teamkill. Now you know why sometime your ambulance is granted teamkill, it is usually the only vehicle driving close to your base fences.
Ostheer: Needs T1 (Mortars) because it can't survive with Pios + MGs only (besides Call in 0CP units like Osttruppen.
Soviets: Need T1 (Penals) or T2 (Mortars) because they can't survive with Cons + Engineers only
USF: Have a Mortar in T0.
UKF: Also lack anti garrison in the early game, still I made experiences that MGs clear out buildings very good if they are also in a building.
A T0 AT-Gun is not useful because you can't get vehicles at minute 0. On the other hand you can occupy the key building of the map in about 15-20 seconds.
Just saying nobody get Anti-garrison T0, now you can invest munition on pios/engy but that's not anymorer T0 at the time it becomes available. It is true that USF get the mortar t0, I just personally not consider it as a good anti-garrison unit, not like flamethrowers or flam-nade, but still my mistake.
About OKW T0 ATG, as OKW you don't need to care about anti-tanks because whenever you decide to go T1 or T2, you already have access to it. This is not true for Sov/Ostheer/USF.
OKW just needa a T0 suppression platform, meaning the MG34 that's already there, without the hindering tech requirement. And smoke, OKW just needs none doc smoke, either on the leigs or on the sturms/volks, but I'd rather go with the leigs or volks.
And finally, be able to build caches. With no unique resource system there is no point in having no caches available since they werent given to the OKW in order to balance their unique resource system.
You can't give a faction as starting unit an Elite troop + T0 best capping unit + T0 ATgun and on top of that a suppressive platform.
