Why is phase run even in the sorcery tree? This rune has no real direction as to who its for....
Mages never liked the original storm raiders to begin with. If I recall, storm raiders was meant to give assassins a chance to escape after going all in. Yet the keystone is in sorcery, not domination.
The most practical use in the past of this keystone was for bruisers like Darius to stick to targets without getting slowed.
The only mages who like storm raiders were Cass and ryze, but even they won't use the new phase rune because it is harder to proc and they get better use from comet or aery.
So my question is, who is phase run for and why is it in sorcery path?
= sustain
player i can tell you I liked the old stormraiders and that I use the new phase rush but I will admit that sometimes I don’t feel like I’m using it sometimes.
and 
Liked it before the change too. There isn't an attack speed tree with it though.
is a dead item- 
; I'm currently in Gold.
was the shit when I discovered it was a thing.
is the only phase rush user I know of that would prefer it over old stormraider's. You hit them 3 times, get the phase rush proc, then eat them and run them back into your team or to your tower. It's a bit of a gimmick but I find it fun.
