I understand the logic behind this change however I feel there still needs to be better counters to aircraft or at least more rewards to fighters that actually shoot down enemy planes and cover their ground units
What pees me of most is, that so many players don`t even bother to mark tanks, or anything else come to that. Maybe we need points earned for marking the enemy, maybe that would sort it out 
I endeavor to mark as often as I can, but tanks are sometimes imposable to get the mark to set on

In that campaign you kill tanks with mortars.
In other campaigns not really.
I don`t normally have any problem with marking pesky Tanks 
The Granatwerfer has 81mm lol?
