Movement Speed Quints

I'm a mid lane main, playing mainly a smattering of immobile mages. I almost always eschew early damage in favor of better positioning potential, hence my taking of movement speed quintessences. My question is as follows: with the changing runes, will there still be a way to add 4.5% movement speed to my champions? I'd be quite disappointed if the potential of increasing the speed of champions such as Lux, Ryze, and Cassiopeia was removed or lobbed in with something like "-% increased movement speed out of combat."

TL;DR Pls don't take away my sanic abilities :-( I gotta go fest
