Concept for an OLAF UPDATE

As i feel Olaf needs to utilize the RAGE mechanic, I came up with this quality of life update for him. I play Olaf on a regular basis, and I feel he is ok the way he is, I just wanted to throw this out there. Olaf would keep the attack speed bonus for missing health in his passive, this is just an add on.

Olaf’s passive now grants him rage (he still has mana) from basic attacking, killing enemies, taking damage over 5% of his current health(this can’t be activated by minions or non large jungle monsters) and damaging champs with spells. At 100 rage, Olaf gains 10% lifesteal and spellvamp.

Olaf’s ult passively grants him armour and magic resistance based off his rage (I don’t have the exact numbers, but something like 15/30/45 armour and MR at 100 rage should work). Olaf becomes unstoppable for 5 seconds +1 second for every 33 rage Olaf has. Olaf’s rage is consumed over the duration of the ult, and he is unable to gain rage from his passive, except by killing a champion. Olaf still gains the movement speed and AD for the duration as always.

Thoughts?
