it can be considered a stun as well since you can't do anything while rooted.
My playing style with Kassadin is slightly similar in rune and mastery aspects, though I usually use Glyphs for cooldown instead of mana, then mana or movement speed in the purple runes (forgot the long-ass name). I usually try to work towards lich bane first, but I also get rod of ages. The +25% ability power ring is also quite powerful too. I rarely get any boots, even the initial set, before my first rod, the Void Walk is just so conveniently powerful. Usually upgrade to Tabi for the dodge and armor, no need for ability power with the rods. I sometimes do get the ability power boots though if it's a bit tough farming in the part between early- and mid-game.
