Haha fuzzywuzzy you’re one of the few people that have now been enlightened, welcome.
ALL IN MY OPINION OF COURSE TAKE WITH A PINCH OF SALT:
Lack of understanding dive kicks and their weaknesses and when you can and can’t move against Yun aids in this sentiment.
Of course he’s a powerful character, versatile per say, good damage, counter poke game, command throw, good meter gain, altering of jump arcs so hard to AA and comeback potential BUT in BO3 or some tournament environments his various playstyles can either go for or really against you (against characters that either do high damage or tricky to get in against).
Unlike other powerful characters before him, he still has to play 2 player with his opponent whereas older versions of characters like Fei in his prime, Akuma, Cammy, can literally play one player.
General consensus is when Yun has momentum he’s OP because of his options but defensively sucks like a toe and takes hits like a schoolgirl.
We’ve all had rounds where we stun someone who the last tenshin into st MP xx shoulder or we cross up dive.
So again he’s strong but we’ve also all had rounds where we’ve gone ham a bit too early or too late.
Low to Mid level (or people that can’t fight Yun) indeed he can look like the second coming of Christ but once the opponent starts countering matches look really different and you have to pick your spots (1-2 at a time) and this is what he excels in but you have to have enough life and do everything right before that happens haha.
In long sets however Yun >>>
Matchups where it’s hard for them to hit him >>>
