Warrior's abilities like Fell Cleave and Inner Beast share the same icon slot and the seam cooldown. SCH and SMN pet abilities share the same cooldowns, but not the same icon slot. E.g. Fey Illumination and Fey Wind. While the CD of Fey Illumination is 120s and Wind is 60, if you cast Fey Wind, then swiftcast summon Eos, her Fey Illumination will be on CD.

A lot of the SB changes were to reduce hotbar clutter, but for some reason pet abilities were neglected.
