What if Nasus resistances during ult were scaling with his number of stacks? (PBE)

Of course in a way that it ressembles the current values on PBE. Cause we all know Nasus very lategame (everyone 6 items) is kind of underwhelming for the iconic infinite scaling champion.

Random suggestion would be "10% of stacks" bonus resistances instead of 20/40/60 bonus resistances. Rewards Nasus for stacking and rewards opponents for denying stacks. Nasus can be more durable by stacking instead of being indefinitely an easily killable champion at 6 items no matter what stacks he has, even if built full tank.

And for the growing value, either keep it at 1/2/3 resistances per second or make it 5% of the initial value (aka 0.5% of stacks / second)

Tbh he'll still be killable, to have more than 100 bonus resistances which is still dealable with he needs 1000 stacks, which is impossible in a decent elo game. He needs respectively 200/400/600 stacks to reach the current values of resistances on PBE, so that's more of a nerf than a buff, though it actually accentuates the potentialities of his infinite scaling, which is the whole purpose of Nasus identity, lategame fantasy.
