That isn't my logic. My logic is that a profession is not the same as a class, cannot perform a class' roles, and cannot take the place of a class. That is an extremely simple concept that you and @
Kumorii can't seem to grasp.
Feel free to show me the Alchemist abilities of Healing Spray, Chemical Rage, Acid Bomb, and Transmute within the Alchemist profession.
Yet they are, and having explosive shot surrounded by animal-based and archer-based abilities doesn't have much to do with a Tinker.
Try Gelbin Mekkatorque. He is a Tinker and pilots a mech. Next up try Gazlowe, who also pilots a mech and leads a Tinker team. When you're finished looking them up, feel free to reference back to the WC3 Tinker whose ultimate ability was the ability to pilot a mech. The reason I attach mech piloting to the Tinker is largely because Blizzard has always attached the ultimate abilities of the WC3 hero to its corresponding class. The Tinker should be no different, and that means that the Tinker WILL be based around mech piloting.
