His heal is reaaaly minor, having way less impact than for exapmple shen's Q health regen. He has no defense "boosters" (shield, armor bonus, anything) and pretty much useless passive. His stun stuns himself for half of given time, but OK, that is good anyways. Gap closer relies on double use, you can hop walls but in gank its not that good. He is mostly earlygame champ.

Olaf for comparision has one of the best clear times with blue (Q almost no cd), this slow IS strong considering how you can abuse picking up axes. Relly, Olaf with doublebuff coming from jungle will lay waste on ANYONE, having supreme damage just coming off 2s cd Q's. But there is more damage, as W gives him sustain and damage coming from HP (allowed building tanky, still has damage). Lifesteal isnt that good but it synergises with passive and spellvamp procs off smite, E and Q, allowing pretty nice health regain. E is simply damage, scaling off CDR which we are allowed to build with tankiness.

AND THAT FUCKING ULT. Look above - Olaf is nice! With ult, ghost and shurelias he is unstoppable beast, teraing any carry apart if played right. Thats why they nerfed him a little lately, but he still rocks in good hands. He is a lategame god just with 40% cdr and fuckton of health.
