Having a unit that can bleed you long range and can sprint away if you try to close in (conscripts with lmgs) does not fit well any Commander.
Disable Oorah ability when LMG upgrade is bought. I think a DP-28 upgrade for Cons in one commander wouldn't hurt the game. I'm all for diversity.
Don't forget there's Panzerfusiliers who can upgrade to 3x G43 AND pick up up to 2x LMG. They're pretty terminator but they don't break the game.
