Bottom 3 character

Nah, in most modern fighting games, the tier lists just don't matter. Whatever tiers exist in Strive are pretty tight these days, and they mostly always have been. You're good with whoever you like. I play a character with a white WA (Goldlewis), so I'm using it more as a neutral tool than a combo tool, but yeah, the general flow is just hit 1, hit 2, special move, red RC, then whatever's good for your character to juggle with. So since you're blessed with one of the game's best 6Ps, stain state confirms, and enormous buttons that win neutral against almost everyone, you're usually doing Slash, Heavy Slash, reaper, RC, and you can just about make up the rest and it won't matter much. You'll get that in no time. Go into training mode, practice it against a bot set to block after the first hit. Then when you've got that down, set them to block randomly so you can practice confirms.
