2v2 and 3v3 isn't going to be balanced. Like Darkmaximus said, 1v1 and teams share balance even though they all require different tweaks. If you made a balance decision in regards to 3s, that would end up negatively impacting 1s and 2s since the thing you're buffing or nerfing was already fine. If you're okay with the game being balanced around 1s though, you should be fine with people using that as an argument not to nerf air.
Actually, no, it's just realistic. 1v1 is more important than any other gamemode or playlist. To call that fact rude and insulting isn't really as "fair" as you could possibly be. Look into why RTS is balanced around 1v1 rather than writing off that line of argument as an insult.What you call "realistic" is still rude and insulting. I'm not talking about the developers balancing the game around 1v1, I am talking about the people who use that fact in a condescending way to respond to someone who wants the mode they play to be balanced as well.
When someone comes here and says that Air is OP and then people make smart remarks that end with "1v1 is the only real mode", that is insulting and rude. It's rude because its dismissive, and it seems that many of the people who reply don't play 2v2 or 3v3 anyway. So why are they even responding?
It's insulting because barring a sale or something, we all payed 59.99 or more whether we prefer 1v1 or 3v3. Until they start issuing a discount for people who prefer the unbalanced mode, then all modes should be balanced. What isn't "fair" about that?
People who play teams and people who play 1s all bought the game for the same price, and they all should have known what they were getting into. If anyone played HW 1 they know that while the game was overall unbalanced, the 2v2 and 3v3 balance was worse than 1v1. The same can be said for a majority of RTS games I would imagine. If you bought Halo Wars 2 without any suspicion that maybe the game wasn't going to be perfectly balanced to your preferences, then I would say your expectations were way too high. A glance at the beta would reveal to you jump pack brutes nuking bases with seemingly no counter play. Of course something like that is going to be worse when there are more than just 2 players in the game. Then maybe you would've either passed up on buying the game or bought it with a more realistic mindset and expectations.
And I hope you're not serious about the discount thing.
Ok. This is the last thing I will say about this to you because I am not sure if you don't understand or if you just want to go back and forth.
I am not saying the modes should be perfectly balanced because that is likely impossible. I am saying that Air is still OP (not unstoppable) because of what you have to do to stop tech 3 air. The process for stopping air is not as simple as stopping other units because the wheel is still broken. If they fix the wheel and make AA better at stopping air, then Air will be fixed in all modes.
As another poster and I discussed in this thread, you have to do too much to stop air. Air is the only unit that you have to do nearly full pop AA to stop Tech 3 Air with healers (especially hornets). You never have to make full pop anything to stop vehicles. You have the choice of making banshees, blisterbacks, hunters, or some of the other vehicles. For air, you must have AA, and a lot of them.
And it is rude to dismiss someones concern with "well it's not a problem in 1v1" when they voice the issue. You admitted in this thread that Air is unbalanced, so I know you know it.
