I wanted to write something after hearing two of my clanmates say that they've had enough of the CVs. I wrote before how I dislike T4 CVs and I still do, and gave up on it after literally a few games. So these solutions may not be the best due to not having first hand experience with higher tiers. Still, I hope somehow even as wishful thinking, that WG sees this and gives it a thought.
Re-enable some of the old controls
Although I think just reverting to pre-rework is better imo, I doubt it will ever be done. The next best thing is being able to waypoint both planes and ships and be able to switch controls using Z as before. That way, it's easier to control CVs during times like evading torps and fire. It doesn't happen always, but it is useful when it happens. Plus, it doesn't really make anything overpowered. And to maintain the current "attack" of the planes, make it same to waypoints of ships which are only for movement. And those planes will fly straight and not dodge AA.
Improve AA/Dmg Scaling
I've seen my posts regarding AA. Some complain it's too hard to dodge and melts planes too fast without even making people reach targets. Some complain how AA is useless and they still get swarmed and it discourages solo ships doing stealth flanking. So here's my take on it, scale it better (damage? Plane HP? I don't know). I noticed being uptiered by a CV made my AA useless. Meanwhile, being uptiered when I'm using a CV made my planes useless. So why not find a middle ground of damage? That's what PTS is for. For another, I'm quoting someone else's idea in here which is enabling captains to pick AA patterns, because the AI for AA is quite predictable according to some people (not me, I don't even see patterns lol). Yes, that adds more work to the captain, but it is completely optional and at least removes people blaming its predictability.
This imo, solves a lot of problems with the CV gameplay and might pacify the angry mob. What if instead of the deployable squadron around the other planes' flight path, a separate squadron is added? (Because spawning planes in the middle of the map is weird) How will it work? It basically is a RTS fighter that you can click to "escort" friendly ships but you can't manually shoot with it (like before rework). They remain automatic just like the other fighters. The difference is that, now, CV captains can actively defend their teams' capping DD. And the Fighters are allowed to deployed while other attack planes are being used (TB/DB/RP). Would it break anything? I don't think so aside from floodgating the CV spam. Only the fighters are allowed to be sent while you're using the other 3 squadrons, so no cross-drop and stuff and no complains from other ships. But doesn't that just make it more of a CV vs CV game? Well, let me ask you, do you prefer no one being able to defend you from the other team's CVs, or have your CV be able to do it? I prefer the latter.
Another factor which I think would be great is Fighter squadrons reduce Air Detection of enemy planes they are actively engaging. Take note active, so it will be balanced, as all things should. Imagine a CV captain escorting a DD that's about to cap. It's a no brainer to enemy team that some ship/s is capping. So they send some planes to that point. But OH SNAP! The capping ship is escorted. Would the pilots have time to spot while being busy dodging bullets? I don't think so. Would that make the DD happy? Yes. Would that make the DD feel that CV is a good teammate? Yes, probably. Would that make the enemy CV happy? No. Would that make the enemy team happy? I doubt it. Would it promote more cooperation with teammates? Yes, considering they know the CV got their back. Would it reveal info on where the escorted ship is? Doesn't capping already do it? The only con is if a CV is escorting a non-capping ship that is trying to stealth flank. Considering planes are spotted easier than the ships.
How will it be better than the current deployable fighters? Look at what happens now, usually it's a damage race between CVs. The others are sheeps ships waiting to be slaughtered. And with how some captains prefer to rack up damage instead of helping the team, that would make it worse. Given how long the 3 plane squads have to travel from A to B + occassional AA fire, some would prefer to not bother at all as it hampers their DPS. But if fighters can be controlled separately, it gives no reason to not help out the teammate in need.
Bonus! They can even make national flavors on them like let's say Japanese have numerous planes but lesser HP because kamikaze. And USN have lesser but tougher.
Non-instant repair for planes
This is more of a random idea. What if planes repair over time? It would lessen plane spam, wouldn't it? The repair time would be based on HP lost and would be lesser than the time to recover planes. But it has flaws, considering you are stuck to sending unrepaired planes if you are spammy, instead of freshly spawned planes from the auto recovery. The game will pick the highest HPs to fill the active squadron ofc and let the lowest HP ones repair at the hangar. I have no idea how this goes, but it seems nice. Realism isn't this game's forte after all.
