Let's talk about the Olaf buff.

Doesn't seem like it'll be too massive (only lasting a second), but it's still something. Thank you, I've been waiting a long time for this.

Any context, though? Is this just testing for perhaps a bigger buff? Are you starting low at one second just to see how it plays out, with plans to nudge it up a bit?

Edit: Also, the tool-tip is a bit weird. Should move the Movement Speed tooltip below the "You lose the passive portion and gain AD" bit. Somewhat unclear when you read it all together.
