Hallo,
1. Medic kit system, my opinion: the automatically self-heal is good enough, however if you add heal ability, in which unit upgraded medic kit can heal friendly other units (with low cost or free) in parallel with self-heal. The idea is to make soldiers share their stuffs, the game called company of heroes, not CO selfish, right!?
2. OKW SS Artiilery doc lacks certain anti-tank in the early and mid game, only small pak guns when you move AT-squad to higher tier 3, can you give them panzerfaust infantry units?
Yours sincerely,
