Can some of Pantheon's nerfs be reverted now that other things have negatively impacted him?

For example, in 4.21 he got his attack speed lowered because of the dragon cheesing. However, not only was dragon changed to be coded as a spell, the attack speed was reverted to previous seasons, where it had 4x the attack speed but 1/4 the damage. So in theory, Pantheon literally got nerfed for nothing in 4.21.

Additionally, could he please get a buff to his ult? It's been nerfed so many times, and at one point it was being considered to change the once global ability into one that could barely got from one tower to the next.

I'm not saying it should be global, but at least let him use spells to get down quicker like with his W, but c'mon. His ultimate is so telegraphed and takes so long literally anyone can casually walk away while you have to channel for a combined nearly 5 seconds, and 2 of which they see you coming. Yeah, it does a lot of damage and slows, but that's assuming you're going to hit it, at least give it some more range or allow him to come out quicker with W, but giving the impact less damage, this way he can get into the fray when needed, but he doesn't keep the 1k base damage.

If all else, at least revert the attack speed nerf from 4.21. Dragon got changed to a spell (which imo should also be reverted) and it got it's attack speed back up, so it would actually be harder for him to do dragon, because the attacking is the same, and he can't block it. So basically Pantheon took an attack speed nerf for absolutely no reason.
