Not really… you throw a bomb that could very well be just you throwing some duct tapped dynamite.
I think the tinker class should be short races focused, with strictly Goblin x Gnome themes.
A Tank spec focused on being in a mech suit.
Healing spec based off Alchemist from Wc3
DPS spec more focused on zone control, building up turrets and structures… setting up Zap gates, Shrink Raying threats, Firing up a SUPER DEATH LAZOR, hitting a nice Grav O Bomb.
Just it is a fantasy not touched… similar to how old demo was those people that wanted to demon hunter but had to play make believe .
