Honestly, as far as post-Vanilla classes go, the Death Knights' case of "like against like" are the exception. Not the rule. Every other new class has been about countering the new threat, while tying in to the philosophical theme of the expansion. Pandaria being about conflict and understanding, and Legion being about sacrifice and perseverance.
If the next leaks suggesting the expansion is about undeath or void, and the narrative theme being about advancement and "how far is too far" and "going where no one has ever even thought possible" are at all accurate... well, that'd be a perfect fit for Tinkers.
