Well I don't hate the angle anymore because of how the move is now. As of right now it actually IS one of the best things he has. It kills earlier than Mario's (even earlier if you're anti-airing someone and they're near the edge) and it has INSANE hitbox coverage, it will NOT miss in front of him AT ALL, as low as crouching G&W (which is incredible). Before 1.1.0 the new USmash angle felt stupid. Now it has a purpose, increased KBG and INSANELY GOOD coverage. Like, really good.
Also damage would just make him annoying to fight and people would camp him mad hard. All I want on Doc is Pills having old IASA back, DSmash killing at the front and not the back, and Fair not having a sourspot at the early hit. D-Throw -> Fair Sourspot is already a thing (the sweetspot is MU specific AAGHHH) but yeah. I think he's really close to being a perfectly fine character honestly, his recovery isn't great but it's not horrible either once you use it properly, and he's REALLY dominant at edgeguarding (especially low, Dair, Down-B, even Bair which has one additional sweetspot frame vs. Mario's and has the power you know it for, it is WAY better than his Melee Bair). His neutral is a bit worse than Mario's (not SUPER worse because he does have a Bair that hits all shields on a SH and it's pretty safe too) he just really sucks in disadvantage which would only really be fixed by retooling Nair or boosting mobility, I'd rather they just made his neutral more stellar.
There, my semi-rant on how Doc is pretty close to being an ok character, really he is! He gets a pretty bad rep in most casual circles but he's not really far from being a solid ok character. His flaws are super evident but funny enough, it's the few insanely good attributes he has that keep me from really calling him outright terrible, which include one of the best OoS options in the game, Doctor Tornado as a move (it's seriously amazing), and Mario's frame data.
I might've put my focus into Ryu as my main but I will always secondary Doc and he's gotten pretty significantly better from the patches overall I think.
