Wario is actually a pretty solid high tier; the reason for this is because he has just really solid attributes. His Hitbox is fairly small but he weighs a lot, which is a extremely good combination for being harder to hit and harder to kill. His Up B got buffed, and in addition with his Bike he has an insane recovery. Chomp got significantly buffed from Brawl, and as a Command Grab that can work in the air, it's something other characters would die for. Bike is just a really good mix-up option, kinda similar to Sonic's Spin Dash, which can absorb projectiles, and also do other shenanigans with wheelies. And Waft is still insanely good for getting kills with it's big range and power. Not to mention he no longer has that weird Grab Release follow-up issue.
The main thing you seem enraged about is his air speed (you don't need to make 3 threads about it). Sure he can't short hop Down Air and weave in and out like he could in Brawl, but he still has the second best air speed in the game. You have to rely mainly on FAir and new DAir to space around and approach with Wario (great for conditioning the opponent to shield, which is a free chomp). It's different however it's far from making Wario bad with all the other strengths he has. (And I don't see why you're saying Wario can only play defensive, he's not much different with the rest of the cast in terms of how offensive or defensive he can play).
