The passive is going to eat almost half of a spell's damage and in return slows the enemy team for it. In a team fight he can potentially just soak up lots of good spells, and global ults are much less harmful with his passive up. Also, a 2.5s slow is pretty... hard. You're basically going to have to walk slowly for almost 3 seconds if you ever happen to poke him. And if you poke him, he'll throw his Q at you with ease. Makes initiation very easy but also makes it easy for the enemy champion to get permaccd - 2.5s Slow into Knockback and Stun.

It has one hell of a cooldown, I know, but honestly it has huge range, ignores minions, decent damage and two seconds of crowd control.

Considering his W deals damage per second, it means every second it'll deal damage equal to the base damage and 45% of his AP. Which, if you have the enemy in W at all times, results in a 135% AP ratio. I don't think ANY basic ability has that insane a ratio. Also that cooldown is pretty weird. 18.19? Change that to just 18 or something lol.

E doesn't need a range since it's a self-targeted ability.

R is broken as shit. It's basically a 3500 Range dash (that's 500 units bigger than Caitlyn's Rank 3 Ace in the Hole!) that you can activate THREE times, so essentially it's a 10500 Range Dash. That's... I dunno, more than half the map? He can almost gank from his LANE. And having this on a 100s cooldown doesn't help it either.

If anything, literally nobody is going to escape from him. You could send him mid and cc the squishy and then jump onto them with R while having E and W on, they could flash away but nope you have two MORE Burrows. And escaping from a towerdive certainly can't be that hard either, you just Burrow or Flash away.

(Minor nitpick: E and R's AP Ratio parts are missing the percent % sign)

I'd suggest like... completely scrapping the ult and heavily changing his passive. I know the ult is what makes Mason, well, Mason, but it's just... far too broken to be fun to play against. If you even HIT him once with a spell Q gets a lot more easier to hit. And imagine when he gets a gank from a jungler... Oh, and nerf the W ratio, it is way too high. If you wanted something like a 45% AP Ratio in total after they've been in the burn radius for 3 seconds, the AP Ratio listed should be (15% AP).
