So hello, as promised long ago to a panda avatar, I am going to post my wishes for a Tinker class. Only we just got it, in stealth, because we were not paying attention to the minor details.
Tinkers can be both melee and ranged, have traps and bombs, use engineering and have mechanical pets. They are not always Gnomes and Goblins, but most are.
With the new Changes to Hunters, and the play style of Survival, with a Gnome and a Mechanical Pet. Using Bombs and Missiles made by Engineering, with all the grenade Talents. We have the gameplay of Tinkers now.
All we are missing now are mech suits that we can wear while fighting. Oh right thats a toy in Legion.
