Nasus needs some changes...
Nasus is one of the few juggernauts who's kit does not seem as cohesive as his brethren. Most of the other Juggernauts scale primarily off AD or a % of their AD is used to determine how much magic damage that ability does or they have high amounts of magic damage with % health damage tied outside of their ults. I think Nasus could benefit from this same concept.
Wither- I suggest we move the % Health damage to his wither and remove the AS slow. Over the duration his target is slowed by 95% and he will deal 5% (+X% of his stack damage) of his target's max health as physical/magic damage. This will give him better affinity to fight front line tanks while being less oppressive to squishier opponents. T
Spirit Fire- I suggest removing the flat Armor pen and give it to his ult. Spirit Fire could have a new effect such as grounding, grievous wounds or leeches a portion of his enemies AD or MS and gives it to him. It should still probably do magic damage but be toned down. Sorry I am too lazy to crunch numbers.
Fury of the Sands- As I suggested above give him the Armor shred on his ult. to give him more potency on the front line where he is most likely to fight against other juggernauts and tanks.
Yes this would probably be a buff overall but really we are just swapping out his % max health damage and Armor Pen to different abilities so his damage and play style could be more consistent. Most of the juggernauts can do %max health off a regular ability where as Nasus has it on his ult, it does magic damage and can not always be in range to make sure he's getting max effectiveness. Wither would be a great way for him to single out a target to fight and give him some power to reliably do so. I mean FFS Darius gets 25% armor shred just for putting points in his E or Garen spinning around in a circle. Putting the armor shred on Nasus's ult will make it so the % health and the pen are not oppressive all at once. He will have to choose to use his ult to kill a single target or save it for a skirmish or fight. It will also give Wither counter play. Do I want to fight the tank and get him low enough to kill or reduce the movement of their AD carry so my team can kill them?
Thoughts?
