Olaf needs changes (again)

TL;DR - Olaf's Undertow (Q) needs a movespeed boost for him when he runs towards it, just to see if that would help his kiting issues and win rate.

I love playing Olaf and the playstyle of Olaf (the low health = stronger playstyle), but I think he needs changes again. I hate using comparisons as to not cause homogenization, but take Skarner or Trundle for example. Closer to 50% win rate. Both have a SLOW and a movespeed buff. They all 3 have aspd buffs, they all 3 have mitigation (Olaf's W's lifesteal, Trundle's AD debuff and ult, and skarner's W and ult). I just find it kind of strange that we're so worried about Olaf's balance that he's remained untouched for some time. Skarner can slow, gain movespeed, and even more movespeed via Q AND Triforce/frozen gauntlet. Trundle can slow an area, gain a movespeed area, stick better with the Q slow AND triforce. Olaf can aoe los slow and pick his axe up, yes, but that's rarely the case, he still has no movespeed buff, and triforce/frozen gauntlet isn't the greatest item for him, because E'ing too much hurts, and he's so item reliant (youmoo's/frozen mallet/righteous glory) if he wants to have that same-ish stick ability. Sinking early gold into frozen mallet or youmoo's is detrimental to his kit and playstyle. He needs the free reign to pick up hydra or botrk first like fiora, trundle, jax, and the other similar bruisers. I feel that if move speed was added to his kit (W is already too heavy with the aspd/lifesteal/lifesteal increase passive) he'd be better in line (at least we could try and see) with other champs. Adding movespeed to the direction he throws his axe would help him stick to people better or decide to throw it in front of him to get away from people like skarner/udyr/tryndamere/others can do just by simply pushing a button. Just having that extra option on him to throw his axe and him go running after it would help tremendously and not break him. Not to mention Q costs would keep that in check sorta like a blue-less udyr spamming away his bear speed.
