I kind of wish every champ worked like Cass: six real items, no boots.
Sometimes I sort of feel like being obligated to get boots on every build and every game gets kind of boring, ya know? If we just gave every champion +45 to their base MS and made the current Boot effects some sort of Runes option you could pick (something like, Blessing of the Rift: gain X effect at the 10 minute mark of the game.), we'd all have an extra slot to play with for item and build combos.
