While cool, something like that is more work and harder to balance
I agree, but I was just saying that adding minor utility to units make them more "appealing" to use. That's the problem I see in many balance threads. People want to "see" a unit more and have fun with it, so they ask for buffs.
If you greatly buff Ostwind, Ostwind rush will be the new meta and people will demand a buff for PZIV and so on.
But by giving units some niche abilities without directly buffing them, almost everyone will be happy.
I'd stay say that for Ostwind, a Lockdown ability which gives it a suppression arc (not 360) with "reduced" range would be a good idea. Kind of like an HMG42 with reduced range. But still, just an idea which won't happen. My point is to buff them by giving them abilities.
For example, after years of release PzGrens are getting a buff which improves them while they operate near a vehicle. That's a great idea and encourage combined arms.
