"It's actually fairly common for mid laners to have no scaling MR, if you look at alot of 'popular' mid lane picks, they don't have it either."

If they're melee, then they get MR per level; aside from Grag, Galio, and Kass who either get it in an ability, have extended spell range, or have damage reduction in their kit. All common mid lane melee assassins get MR per level, also melee ADCs, Fio, Yi, and Trynd get MR per level.

riot's policies and guidelines for champ creation seem to have changed, most likely due to the bruiser/fighter/tanky dps changes that will be coming in increments.
