He no longer has kill confirms of guaranteed combos off u throw, no. Especially not at low percents. Although you can sometimes get a uair or fair at mid percents I feel, may be DI dependant.
Don't throw around the low tier card despite that though, literally every other move got a buff. Not to mention everyone having universal frame 3 jumpsquat, landing lag on all Aerials cut in half, and having his initial dash go from worst to...amongst the best (and a huge increase in fall speed, dash speed and minor air speed increase) Bowser is a force to be reckoned with. Much better than 4, but he's gonna be underrated for a while until the "no good u throw" stigma dies.
For reference, I went from pocketing Bowser to full out maining him in this game due to the buffs. I got 7th at the first local in my area going almost all Bowser, never could i do thay before. But...i get it. I didn't think he was reedemable without u throw shenanigans lol. Ironically, I ended up not being able to adjust to my old mains well at all (Luigi, Mewtwo) they are now the pockets...
Sorry, got off topic. Hope this helps.
