From hearing all kinds of next expansion tinker related hopes and dreams lately, its got me kind of hyped for the possibility and I thought I would share some of my thoughts for a ranged spec for the tinker class.
Firstly if it does have a dps spec I do hope its ranged and not melee, we have far too many melee specs in WoW atm. Following the general theme of it involving robots and such my first thought is that the three specs, Tank Healer and Dps, hopefully, could have a new weapon type, a Plasma Cannon. The class would need to be a hero class and start at 120 for that though, so Blizz don't have to backfill low levels with these new weapons. Its what it sounds like, essentially a chunky gun that shoots plasma rounds. It would work for all specs because they would act slightly differently depending on spec, for tank it would allow them to pull from range and aggro mobs from range, they would still fight in melee range though, not all tanks use shields after all. For healer they could simply shoot healing plasma at players with ranged talents. Finally for dps, it would work similarly to the guns in game (but abit cooler). Could just use bows and guns but that's abit boring for a tinker class.
Talents /abilites for the Ranged Spec:
Ion blast - a suped up cannon shot from the plasma cannon
Iron Star - Roll a mini iron star, like the iron horde ones, that lock onto and chase targets
Lazer Target - Call in an airstrike on a location
Mecha March - basically the trinket legion proc, a mech squirrel or chicken or what not, that works like the Murloc toy, a march of little mech robots that explode for AoE
Lightning Rod - A placed lightning rod that pulses and shocks targets in an area
Pet - Basically a larger version of the DmF tonk or the zeppelin that acts as a controllable pet, like hunter or warlock pet
Mecha Missile - Fires a single rocket that does burn damage
Tinker Tank - Transform into a tank for X seconds, think Bastions ultimate in Overwatch, big Cd ability
Would definitely roll a Tinker if it is even remotely similar to anything above.
What would you have if you could have a ranged tinker?
