So Olaf is getting a buff on his ult that will increase his movespeed by 50/60/70% for 1 second when his ult is activated when running at enemies. I've seen a lot of people complain about how short the duration is. IMO you aren't looking at the big picture. If you combine this MS bonus with 
you are able to chase down opponents for a VERY long time, so i ont feel the need for the MS bonus on his ult to be any longer than it now is.
Lol I am just happy about the fact that he is getting a buff
BROOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
NOOOO!!!!! people will probably start playing him more

Needing an item to actually make use of the bonus from the ult doesnt make it good.
Im waiting until i get a chance to use it, but I believe that it is just too short. 1 second is still not enough time to overcome the majority of gap-openers that champions have.
You're not taking Olaf's Undertow (Q) into account. Yeah they can dash away, but if you land that at any point, they'll still be slowed afterwards. They won't have anything to stop him since he can't be cc'ed, so they have no choice but to burst him down or hope to run away, unless they manage to get over a wall. As for kalista, I don't have an answer for you, she can pretty much kite anyone to death if played right :P
I would much rather he get 20% movespeed when moving towards his axe
