450k Nasus mastery here with a suggestion(s)
Ok, as the title says I've played a lot of Nasus. I concluded that he's far from viable and I have a suggestion. The first thing I thought of was combining W+E into one spell, and replacing the other one with the new (useful) spell, but that would seem like a rework. Secondly, Nasus' ult damage is scaling with percentage of opponent's health AND NOT HIS OWN, which doesn't make sense. His theme of Juggernaut should give him at least one spell that scales with HP, and ult is the perfect for it since he grows bigger after casting it.
Now these two probably seem like straight up buffs, and they probably are. The only thing that would not be considered a stat buff of any kind, yet QoL change for the doge would be utility change. What comes to my mind about it is applying ''Grounded'' effect on his E (Spirit Fire). The spell scales with AP, and is left out there for the AP build, as majority of old champions had such kit. However, a long time has passed since then, and most of them got reworked (some even several times), but not Nasus didn't. This implies that this spell is probably the most underwhelming spell in the game, and empowering it strays from competitive Nasus build, which we all know is full tank.
Thoughts on any of the suggestions?

. Darius has no form of % health damage while Illaoi's W deals % max HP on the target, but not her own. Even 
deals % Max HP of the target for villians. Volibear and Sion are the only ones i can think off that scale off their own HP in some form (sion shield), but Sion still deals damage based off target's Max HP.

) Since the mastery changes Nasus received a "soft-nerf." Most of the mastery changes in the resolve tree (what use to be the tank tree) do not greatly benefit Nasus. It use to be that I could put most of my points into the tank tree and draw some type of early tank benefit to survive the early game. Now most of the tank tree masteries outside of Runic armor and the tenacity mastery do not really benefit Nasus. Strength of Ages is probably the best mastery from that tree for Nasus, but Grasp of the Undying is so useful in early trading. Grasp, however, doesn't scale well and becomes relatively useless by the early mid game. I would like the SoA to be worth the keystone mastery for a top laner and it simply takes too long to draw much of a benefit from it as a laner.
would literally render Nasus to simply a meat shield regardless of his stack count. Other juggernauts such as 
remain highly effective throughout the game even if they lose lane. If I farm effectively AND maintain a high stack count I should be rewarded for my terrible early game. Most top laners simply out scale Nasus until Nasus has stacks and by the time he has enough stacks it may not even matter it the enemy comp has even a moderate amount of CC. It isn't even about levels because a level 7 Nasus can still lose to a level 7 riven he didn't stack well. My suggestion is to attach a passive to the Q stacks that increases Nasus' tenacity by a small margin for every 100 stacks. It doesn't need to be a lot, just something to somewhat mitigate high CC comps. I am really tired of just two champions such as 
and 
in a comp making it almost impossible to play Nasus. I know that if I hit 800 stacks in a game and we aren't winning we will probably lose because the game went on too long and the enemy team knows how to effectively deal with me.
