Debatable. Type 99-2s hit really hard at the moment, even with just two of them. They’re on par with Hispanos.
It’s definitely slower, but I reckon a J6K could out-dogfight a Mk24 without much difficulty, the late spitfires got way too heavy as a side effect of still using an outdated airframe.
At 6.7 it is very overtiered.
Functionally just a worse J2M3 atm.
I’d say A6M5s are overtiered by more than .3 or .7. Their engines don’t even push out 1200hp and yet they see F2Gs and Yak3Us. Their one advantage can be entirely negated with some care.
Early Ki61s are fine, the issue is all the ‘late’ ones - Hei, Tei, and the 61-II. First two have same flight performance as the 3.3 one, but sit a full BR higher due to slightly better guns. Ki-61-II is a Ki-100 sidegrade that sits .7 above it.
Honestly you could drop the J7W to 4.0 and it would STILL suck. It has significantly worse flight performance than the XP-55, only the guns are an improvement. It’s been in dire need of a flight model rework for YEARS.
Ki-84 Hei could easily go to 6.0 especially now that the japanese 30s got a pretty substantial nerf.
These aren’t the only ones though. Ki-43-III is a pretty bad one, mostly the same flight performance as the 43-II, but sits 1.3 above it because it gets a pair of 20mm cannons which aren’t even THAT good. Its BR comes from when it had an extra ~300hp, but that got nerfed a while ago.
Pretty much all the 2 engine fighters are overtiered, with maybe the J5N and Ki-96 being exceptions.
The N1K2-Js are simply too slow and too heavy to really be 6.0 aircraft, they’re overweight compared to what they should be.
Or just… bad. Seen quite a few players that just make huge mistakes and end up at low speed, within 800m ish of my A6M3 or A6M5 and at that point there isn’t much you can do. Or fall for the ol’ “dance in front of their guns” bait to get them slow.
