Not bad, sort of reminisce of one of my builds. I think it might be good for dominion.

I like this build in dominion, It is SO much fun to run across to the other side of the map at 600+ movespeed and knocking 3/4 of an enemies HP in half a second.

In this build guide final items total 5, not that I have ever completed the 5 in dominion but for a 6th item I would get something like shurelya's reverie to keep into the theme of maximising movespeed, that item for quick reference increases movespeed by 40% for 3 seconds upon activation for you and your surrounding team mates with a 60 second cooldown

I enjoyed and am still enjoying this play style so its a +1 from me :D
