I don't find it as OP but all officers should give a buff to units around for the cost of power.
Perfect example is Command PzIV. It gives bonuses but it's less useful than normal PzIV. Ary officer gives some "buffs"
yet it's useless in fight.
This rule does not apply to OKW. Terror officer, buffs and very good at max range.
Command Panther - Panther on steroids.
Command King Tiger is coming as well.
If you want to buff units it should come alone with decision if I want fightning unit or buff unit, not both.
For example, why Terror officer gives buff and it's useful during battle while commisar has no use with his dps?
But that's just my opinion about officer units.
Buffs or combat, not both.
But like I said, I don't fing Command Panther OP.
