My biggest problem with the game so far is that I really hate the new characters. I hate fighting against them too. Doesn't hate that Manon is completely busted and you fight a lot of them at Diamond +.
Who are you playing?
For me Marisa and Ken are by far the most popular opponents. Followed by Juri/Cammy. Manon and Marisa don't seem too busted to me, more like midtier. I think Ken, Juri, Luke are a cut above the rest atm.
Manon is super busted IMO. At least in high plat/low diamond she's just braindead. If it were up to me I'd have medals reset between rounds, or have her lose a medal when she gets thrown, or decrease damage on her command throw. As it is, if you guess wrong on 2nd round Manon you're basically losing 35% hp on one 5f input, no meter or drive gauge required.
Plus, she has great buttons, one of the best uppercuts in the game (2+HP), good range on normals (her 5 MP is one of the most obnoxious normals in the entire game plus it leads to a braindead 50% mixup), a decent sweep, good corner combos, etc. Her only weaknesses are lack of corner carry and an invincible reversal. Any player who picks Manon and isn't instantly Diamond in their placement matches is utter trash.
I play as Ryu and it's a world of difference. He's not bad but not great either. I'd put him at low B or high C tier depending on your reactions (I'm old so my reactions are shit). Ken is pretty much 100% better in all respects. But I like the way Ryu looks and I really like this game's version of Shin Shoryuken, so I'm sticking with him.
