The UKF planes ain't exactly any less oppressive. The one that comes on the forward base is pretty strong and can wipe full support teams.
Anyways, build a centaur. The centaur and the ostwind are the most capable lategame units which are also good at AA.
I dont want this to become a "But X has it too!" back and forth, if a mod could change the title to "Skill Planes" it might clear some things up.
No skill plane should be aple to fully wipe something that is trying to get away, unless of course they are on low health, a faust + an AT strafe is a dead tank and its very silly (there maybe other combos from allies side equally as similar).
I get that I can get an AA unit and stop it but its never just as easy as that, this could be late game where popcap is so tight, you can't afford an AA unit, until of course, the skill planes wipes one of your tanks
In my ideal solution the AT strafe and similar would be targeted similar to the walking Stuka so you have to predict the path of the tank with 1 pass, if the tank is in that and doesnt move, by all means kill it, its deserved, just to make things less click and win.
