I wouldn't agree, and this is not a cherry picked scenario, enemy CAS does do their job quite well.
On Pavlovsk it's easy mode once you take out the quads. The rest of the game involves hiding from the enemy tank, until it drowns itself, every time. Tanks with a top gunner that actually go on land would make it more difficult for hovering. Having the entire enemy team fire at you would actually make more sense.
IMO the changes melon implemented server side a few patches ago to fix the maps should've been released game side. Also the spawning is not what it used to be, all maps feel like a breeze these days, as if bots are a) not spawning on intended flags, and b) spawning less frequently.
The thing that I miss the most is the neutral time, previously melon made it so that when you reach 0% cap the flag would stay in enemy control for about 15 seconds, long enough for them to spawn and push back the cap, now it when it reaches 0 it's immediately neutral (like it was before the change).
Also the harrier in hover mode is just a fun mini-game inside the game itself, learning to fly it and utilizing it to maximum effect is an extremely fun and challenging task (at least it was for me, and round where are I don't die in it are extremely rare).
P.S. Friendlies shoot more at me than the enemy
