As a 101 mage, the only minions I can get for follower quests is water elementals. However I got an epic equipment from paragon rep crate that increases my chance to complete mission by 20% if a minion, other than water elemental is attached.
Yea sucks cause i am always looking for some twinks to farm together. Most of the time we are running with 2-3 twinks and talking through discord so its not so boring as alone
