Olaf Rework Idea

Passive, Ragnarok: Olaf does not have a mana bar, instead he gains rage from hitting enemies with autos and spells or getting CC'd. Slows generate more rage than auto attacks and stuns/knockups/suppressions generate more rage than slows. Once Olaf reaches 100 rage, he enters Ragnarok. Once in Ragnarok, Olaf gains 100% CC immunity for 2/3/4/5 seconds at levels 1/6/11/16 and gains bonus effects on all of his abilities. Ragnarok lasts 2/3/4/5 seconds but can be extended by staying in combat up to 6/9/12/15 but the CC immunity does not extend through this.

Q, To battle: Olaf shouts a battle cry, giving him 40% move speed when moving towards enemy champions for 2 seconds and his next attack will cut his enemies leg/tentacle/tail and slow them for 40% for 1 second. When in Ragnarok, Olaf gains 60% move speed instead and his next auto will cut deeply in their leg slowing them by 80% for 1.5 seconds and deal a bleed for 8% of their max health over 1.5 seconds.

W, Vicious strikes: Olaf's thirst for battle increases tremendously, giving him more attack speed and lifesteal based on the enemies AND Olaf's max health. He would heal for 3% of his and 3% of his enemies max health for every auto and deal the bonus damage to steal 3% of their max health(note if the enemy is stacking armor, he would heal for whatever the bonus damage after resistances was). This lasts for 4 seconds. While in Ragnarok, the heal is doubled, his attack speed is much higher, and the duration is increased by 2 seconds.

E, Reckless Swing: Olaf empowers his next auto(does stack with his Q bonus attack), increasing his auto range by 50 and swinging with such force towards his enemy that he loses 3% of his max health and deals true damage. The damage is based on Olaf's max health and his total AD. While in Ragnarok however he will deal more damage and reduce his opponents armor by 30% for 3 seconds.

R, Glorious Death: Olaf wants to die in battle but he wants to die fighting hard. Olaf leaps towards target enemy champion, gains 8% damage reduction for every enemy champ he landed near by his initial target by 600ish range for 3 seconds. If he activates this move while in Ragnarok, the damage reduction is increased to 10%, Ragnarok is extended by another 4 seconds, the CC immunity is extended by 2 more seconds, and now he can get the CC immunity again if he kills an enemy champion while he is currently immune to CC(Think Darius ult resets before level 16, he has a set amount of time to use ult again for a reset and if he doesn't, he loses his chance. Olaf can only reset once instead of up to 5 times).

Looks fun, would make him a huge diving fighter but the numbers probably need a lot of tweaking. Maybe he doesn't need to scale off of his max health for damage on his E but I thought he should so that he doesn't have to build only AD for damage on abilities.

PLEASE GIVE FEEDBACK, I REALLY WANT TO KNOW WHAT CAN BE IMPROVED ON.
