This is exactly correct.
I played CVs, cruisers, destroyers, and battleships before, after 0.8.0, and after the hotfix. I consider myself an average player - check my stats. Here's my take:
Before 0.8.0 CVs were boring and disadvantaged (until we limit shells on ships, CVs need unlimited planes).
After 0.8.0 (but before hotfix) CVs were almost perfect, but were definitely at least a bit OP due to the F key abuse. Some complaints were warranted, as there should have been a consequence of flying into cray levels of AA and just "escaping" with a click. Anyone saying CVs were underpowered after 0.8.0 just needed to master the learning curve.
After the hotfix CVs are clearly underpowered and NOT fun - it's ridiculous that squadrons can be annihilated after one attack run. There's no escape from certain death when attacking even one battleship for at least 75% of your squadron. The hotfix took what should have been a small nerf WAAAAAAAY too far - the answer is somewhere in the middle. Allow for about 1-2 seconds MAXIMUM of AA fire on planes after pressing the F key - that would mean 2-4 planes lost when a mistake is made, which is a decent penalty, but less than the TOTAL SQUADRON ANNIHILATION faced now. This way CVs remain fun, mistakes are punished, but not a return to de-planing as before update 0.8.0.
Now, here's my analysis of why we are where we are: There's a certain minority of players who are toxic and want CVs removed. They seem to enjoy being toxic and many also want DDs removed. They never want to change tactics and try to avoid torps dropped in the water. I've seen them in-game. If you're in a BB and don't change course for torps, you SHOULD get nailed - and nailed HARD. I sincerely ask Wargaming to STOP LISTENING TO THESE PEOPLE. They are absolutely TOXIC, they are a VERY small but vocal minority, and they will eventually call for CVs to be removed, and after that, they'll call for nerfs and REMOVAL (!) of DDs because again they don't want to avoid torps. Please make this game inclusive for people who want to play WW2-style naval warfare, which includes carriers and DDs.
And a simple message to those people who keep screaming about "oh we don't have the option to play a game without those irritating planes anymore" - well you DO have an option: Play WOWS tiers 1-4. That's the dreadnought era when planes were minimal. Don't ruin a WW2-style game for players who want to play it to suit your whims.
