After all that debate and discussion on the forum, it never happened. Given how WoW tends to not release classes very often, have people given up hope of ever seeing the Tinker class in game yet?
Me personally I would love a Bard/Musical class. Dark Age of Camelot had 3! One for each faction. They were:
Bard - healers with great CC and pulsing group buffs (could choose 1, like auras)
Minstrel - think a musical rogue fighter. Could stealth and climb walls. Could crowd control and temporarily ‘charm’ high level mobs to fight with them.
Skald - Warrior musician. Would fight toe to toe and offer combat support.
Some of these would be great for WoW. But I guess it will be years before we see another class after Evoker?
