Careful now, you bias is showing!
You purposely ignore that CAS players have to make the decision how close they wanna get before dropping a bomb, all based on their plane’s speed, turn rate, whether it’s damaged, any trees or other objects you risk hitting, and how much risk is associated with getting close, and then they need to accurately place a bomb within 10ft of an, often moving target, considering the target’s speed, and both your speed and the angle you’re coming in at, (and the difference between your nose’s angle and your prograde) and also factor in your bomb’s fuze to place it 1.5 seconds in front of your target, and hope that target doesn’t change course, just for a single kill that would take less than half a second to get in a tank.
But before you can even get to the bombing, you need to get yourself lined up with a target in the first place, and this requires spotting a viable target, spotting any threats (either SPAA or CAP) within a 360° area, deciding whether you should engage or avoid this threat (both of which often mean disengaging your bomb target), and then actually successfully enacting that engagement or avoidance (easily the hardest part of playing CAS), which 9/10 means facing off against an opponent with literally every advantage under the plus size Christmas tree, and then ONLY AFTER >sucessfully< doing all this, can you start a bombing run, and just PRAY TO GOD that another SPAA or plane doesn’t spawn whilst you’re focused at flying you plane 400 mph towards the ground to drop an explosive on someone who may or may not be shooting at you, and getting put alive.
Meanwhile, SPAA only requires having basic lead and bullet drop skills (something EVERY CAS or CAP player already needs) and (if we’re really tossing in bones) some basic positioning “skills” (not really skills, just simply not sitting exactly where you spawned), which is something every ground player should have anyways.
.
TL:DR
I’m not saying CAS is super hard, or that SPAA is super easy, they both require their own share of skill sets. I’m simply saying that your choice of words was extremely biased, and thus isn’t a valid argument.
And btw no, I don’t expect you to read the first 3 paragraphs. I’m not gonna bother proofreading either.
