Am I the only one who as a c/c uses consumables? I find it great in when a zerk drops that haymaker and only drops sanc to smoke a herb and have it back without leaving combat. Sure it's not level 50 but it's not me fleeing to go rebuff. On my paladins I used to use them all the time to preserve mana for combat.
Invokers are quite dependable on consumables, perhaps more than melees too.
