Bait used to be believeable lol. But hey, I like fishing, so I’ll take it.
I can turn your entire argument around, and it’ll make just as much sense, depending on your biases. You say, “SPAA only requires an extremely basic understanding of lead and bullet drop”, and I say CAS only requires an extremely basic understanding of lead and bomb drop.
Meanwhile, as an AA player, I first have to find a suitable spot where I can A) properly observe the sky without leaving any blind spots for CAS to sneak up on me, while also B) making sure I’m not in view of enemy tanks, which I’m often unable to defend against.
Then, assuming I don’t have radar, and let’s say I don’t, since you’re also basing CAS’ difficulty on not having a bomb computer (which would handle most of the targeting for you), I have to find and identify a target. This becomes increasingly difficult at higher BRs due to faster planes, and I also have to hope for good weather to get a clear view.
Next, I need to accurately judge the plane’s range and speed. Depending on the ammunition I’m using, and its velocity and drag, I have to calculate the correct lead and only then do I get to fire. But if I shoot from too far away, the plane has enough time to dodge. So I have to decide whether to risk letting it come closer, for an easier shot, while risking that the CAS will kill a teammate or me, or try for a more difficult shot at range to prevent it from dropping its bombs.
TL:DR
I’m not saying SPAA is super hard, or that CAS 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.
Your entire argument is based on CAS vs AA, which just isn’t the case most of the time, a regular tank has absolutely no way of defending itself against a plane. Period.
And no, getting a radar or even missiles doesn’t eliminate all skill required for AAs. It just means adopting an entirely different set of skills. The lead indicator isn’t 100% accurate, the slightest manoeuvres will throw it off, you still have to manually adjust your aim to land hits. In fact, I often find it easier to avoid locking onto a target and just eyeball it.
Same story with missiles. IR missiles either have a pitiful range or are defeated extremely easily. And line of sight guided missiles actually are hard to aim, again, the slightest manoeuvres make tracking and leading very difficult.
Second TLDR
CAS should be, in my opinion, high risk high reward. You should be able to take out an entire team on your own, BUT, it should require a lot of skill, you could just as easily be shot down before you manage to do anything. There should be an imbalance, but not towards CAS, as it currently is.
