Well no, you just said it was childish and left it at that. Now that I know it's just your opinion based on no real reasoning, I fully understand your position now.
We're very far past WC3 yet the last expansion class (Demon Hunters) released 4 years ago originated in WC3?
We got multiple NPCs and classes in WoW who have new abilities that originated in HotS.
If you want to know what Tinkers could do as a class, all you need to do is look at the abilities from the WC3 and HotS Tinker heroes. They range from mech piloting, to Gravity weapons, to laser beams, to sticky bombs, to a variety of robotic summons. In short, something different than what's currently in the class lineup, like the glut of Shadow-based specs.
Yeah, we get it, you're just expressing your opinion. While you're doing that I'd like to point you to a poll on this forum of a Necromancer vs Tinkers;

Yeah, I was pretty surprised as well....

Actually we had a rather large boost in the theme during MoP with Siegecrafter Blackfuse.
