There are some good ideas in this thread (particularly getting rid of Relief Infantry) but, there are too many OKW units included. Transfers between factions is something to be avoided.
The only one that makes sense is having Fallschirmjaegers in a Luftwaffe doctrine but, they would need to be reworked into an infiltration unit (MP40's with upgrade of 1 FG42) to make sense within the faction.
Lower CP requirements for Smoke Bombs sounds fair enough. It's only in a few doctrines, it costs munitions and Ostheer has access to other smoke options. It's not something likely to be abused.
A buildable PIVF1 is a good idea (T0 after BP2 would be my preference) but, the Command version should stay doctrinal.
Most of oootto92's ideas sound good but, I'm not sure about the Light Barrage. A 20 - 25% reduction might be better; 50% just sounds like too much.
Vipper's Mechanized Repair Team sounds interesting but, I'm curious about the mechanics of it. Are they tied to the half-track or can they wander the map on their own?
And, I'm not going anywhere
near KiwiBirb's dump, let alone touching it.
