Cadet, no offense, but I actually main the character.
And just to kinda recap on what you've mentioned, Jab isn't as amazing as you've made it to claim. It's good at edge guarding specific characters with already bad recoveries. The only use that it has over Dair or a meaty Nair in that regard is that it's player friendly. You just sit there and hold A without actually having to space the Dair properly. Or think. As for being an actual jab, there are much better ones. Meta Knights jab comes out on frame 7, meanwhile we have frame 1 jabs that can't be SDI'd out of, and actually lead to combos, follow ups, kills, positioning, et cetera. Meta Knights jab does none of this. It also leaves him semi committed to the attack.
Dtilt is also not better. First off, I'm not sure what was changed, but I'm going to assume his IASA frames on his Dtilt were nerfed. He can't use the move consecutively as rapidly as he could before. It also doesn't inch him forward, an effect you took out that was already in control of the player anyway. As for the new "pop up" mechanic, Dtilt leads to easier combos, not more useful ones. In vBrawl, Dtilt could lead to a trip, to a grab and throw + pummel damage, then a follow up just by predicting air dodges. While these were not combos in vBrawl, they were consistent enough to use in game play, and with Brawl-'s new mechanics, would have been guaranteed. In Brawl-, Meta Knight gets a Dtilt to aerial, and then it resets the playing field, all providing the opponent actually knows how to DI mind you.
Shuttle Loop, Fsmash, glide attack, and the throws, I agree with.
