Does anyone remember what it was like having that mage in the group who was a complete machine with his sheeping?
Or, inviting that Bard that was a complete pro at his lullaby timing that it made everything go 50x smoother?
Or, that illusionist that was famed for his ability to distract a group of 7 mobs perfectly while your group could more efficiently whittle down one at a time?
It was a very functional, fun, diverse pseudo-fourth-role that broke up the monotony of the tank-healer-dps trinity.
Please bring it back. Sleep, Repose, and Blizzard 2 were all poorly implemented and not fun.
