Nasus rework idea to put him on par with other champions

Passive: No changes, it's simple yet effective.

Q: It's his main ability so it needs some love. New: Bonus damage can now critically strike. New: Now refreshes the duration of wither on the target.

W: A strong spell, but it's cast range is too low, making it useless against ranged opponents. New: Cast range is increased by target's attack range. So it will have 1150 cast range against enemies with 550 attack range and so on.

E: A good spell with the armor shred that goes well with his Q, but it needs to combo with his W too. New: Withered enemies are snared while inside the zone.

R: It's a good ultimate that simply makes him very hard to kill. But it sadly doesn't address his main issue that is getting cc kited to death. New: Nasus is immune to crowd control for the duration.

Aghanim's scepter upgrade: Siphoning strike will now make Nasus leap to his target (600 range).
