Personally I am very excited for a potential Tinker / Engineer class, but regardless of whats to come in the next expansion, the idea of a new class raises a few problems.
Would Tinkers (or any other hypothetical class) Start at a high level like a Hero class?
On one hand, a higher starting level promotes more people to try the class, making it more readily accessible to modern content. A higher starting level would also Circumvent problems like Legion questing involving artifacts and an order hall, and prevent blizzard from having to design a leveling process for the class.
Alternatively. Starting at level 1 means more time /played. This could potentially condemn the class to the same curse as Monk, since nobody wants to re level all the way to max for an Alt character they may not even like. However, starting at level 1 would promote blizzard’s supposed “Level squish.”
As for an order hall for legion, I personally wouldn’t mind if it was something VERY barebones and stripped down. A mission table with some followers, and all zone-essential quests being given out by a single NPC, instead of having an Order hall storyline.
Thoughts?
