Much Needed Additions to Rammus

I was playing Rammus jungle today. So I get my Gromp at lvl 4, and move to River to get Rift Scuttler. I'm at about 75% health and just before I finish killing Rift Scuttler- the enemy Quinn strolls into River at lvl 3 and ~30% of her health. I immediately make my move, but I can't get near her. She shreds me down to ~50% with the kite, so I Powerball and turn to run- tell me how she manages to keep me slowed and keep the chase for a kill. I mean- you can say whatever you want about Quinn- but Rammus should have bee able to survive better than that.

I have an idea to improve Rammus.

For his (Q) Powerball- (as an addition) Rammus kicks up the ground behind him, slowing enemies directly behind him a short distance and damaging them slightly.

For his (R) Tremors- (as an addition) Enemies in the AOE have their movement speed reduced.

Rammus isn't a strong tank when his Defensive Ball Curl isn't active. And Powerball takes some time to pick up speed and is deactivated once you hit enemies, which can make it a bad tool for escaping. With the update in masteries, I can't do a full-tank mastery page for Rammus, so it's about the farm.
