The warlock did have that second grenade but was switched with one of the hunters grenades due to community feedback. I'll think of something I can change, the cluster grenade had to be somewhere and each class needs a basic first grenade that would be effective in PvE. Sunsinger and Voidwalker are very grenade based, so Aeonbreaker was not speced for grenades that much... I could rid smoke grenade for something more useful, maybe something that halts movement that could assist during Super. I'll try to think of something.
