@Mutsuki-chan you can spawn directly on the Hind/Condor and/or MAV as long as a seat is open.
the spawn beacon was chosen for specific vehicles, the RAM's beacon can be destroyed by enemy forces even.

I agree though the balance is so far out of proportion is crazy, but its not absent, DICE just does not know what its doing. I don't think they even have anyone who is a qualified tactical advisor on things like this, they literally just guess. Hell, I'd take that job, given my background.
AA needs a dedicated category, too many players have the Wildcat configured in a AT/Infantry role while trying to fight aviation, or in AA Config trying to focus solely on vehicles. This ruins any chance of viable dedicated AA Support on maps with just 1 Wildcat. We need a dedicated AA Platform.
"Engineer class is not picked often because their skills are not so good."
^ ^ This is false - Engineer is the second most used class, if not THE most used class. you cannot tell me nearly every single match i see 20+ Rockets flying in all sorts of directions within a time span of 30s-1m - that Engineer is not used. thats just not true.
"The 20mm gun cannot kill an infantry untill 3 direct hit to their human body, that's rediculous." If you are referring to the 20mm of the Brawler, that's because its a AA Flak Gun, its meant for Anti-Air. though a 20mm round slapping your body should turn you into a pink mist pile of splattered goo, but we cant have that. We cant even have OHK Headshots from sniper rifles or any firearm for that matter !!
30mm is the guns you are referring to if not the Brawler. like LATV, M5 and MAV, they have 30mm HE, and again, because it would simply be too easy, that HAD to be balanced out to take multiple hits for TTK.
