Tinkerer will be the new class in The Last Titan with Mimiron teaching the ancient knowledge of Order-based engineering to mortals. It will feature a unique, mostly just for fun mechanic where multiple Tinkerer's can 'combine' their big cooldown for a very slightly enhanced effect.
Specs will be Gunner (ranged physical), Electro (ranged magical) and Machinist (melee)
They will have a unique, mostly just-for-fun ability that allows multiple Tinkerer's to 'combine' their big cooldown ability for slightly enhanced effect but Blizzard will stress that players shouldn't feel forced to coordinate if they don't want to
