[Opinion] Skarner "Runes" Build

So here's what runes have been working for me as Skarner. It's a little softer than I'm used to building him, but he has stronger initial burst plus pretty good movement.

Primary: Sorcery

Phase Rush- pretty obvious why, that extra boost of speed if you do it right is a lot of extra distance on his ultimate. It also gives him amazing running away ability having only need to use E>Q>AA for not only a stun, but an additional burst of speed on top of this passive.

Ultimate Hat- do I really need to explain why I would want more Skarner Ults?

celerity- that extra 4% with everything else is great. Not to mention now movement speed adds some damage.

River Walker- even more movement and attack in rivers, where Skarner will shine most of the time anyway for Dragon fights or Baron is a great edge.

Domination:

cheap shot- so many immobilizing attacks it only makes sense.

Relentless Hunter- This extra boost was allowing me with everything on top on average 550~600 MS at times.

Also, I have noticed that with these new runes he has a better presence in lane again than he does in the jungle. I've seen some people try to use Burst build Skarner but end up exploding because he's not fast enough to get into positions he needs. Let me know what you guys are using too.
