Is it worth returning?

Just halve fighter HP, buff spinner's damage and AA turrets range, then air should be perfect.

At this point I'm thinking targeting priority would be OP.

Epic imbalanced might have been a little too much hyperbole

Sounds like the recipe for an overnerf.

Instead of trying to make hp and damage values work for broken targetting I'd just add reasonable targetting instead really. Yes bombers will suck at attacking AA. As they should.

I agree, after which if air is too weak, a health buff should do.

Edit: But please everyone must learn this, doing more than one balance change can often have bad side effects, you must slowly iterate unless you're very confident in your decision as it normally ends up as a double nerf.

Longer Answer:

The game is none of the things you are asking for yet. 1v1 exists but isn't the most exciting balance. Balance is really just tanks for base smashing despite enemy defences and density, bots are for most of attacking as they amass and destroy expansion, air mostly counters bots as a couple can sweep a dozen dox out of existance.

It is competitive but not really provoking on a deep level, just a interface speed skill level, as far as trying to order things through a perceptive enemy quickly.

I would recommend it right now only to someone interested in learning, modding, casuals, or more manually set up games like the 4v4 clans are doing.

I would not recommend it on the specifics you requested, unless you are interested in checking it out, seeing exactly where it is and isn't good, all the while learning how to quickly play the game hotkeys and all, and also submitting your feedback on what could change to improve.

There is nothing more annoying then to see your rockets swirling around at the back of an airplane and not doing anything...
