Origins of the Timewalkers
The Timewalkers are a new faction in WoW that was mainly in a few TCG expansions, it was their job to 'police the timeways' after the Bronze Dragonflight became more 'mortal', after the Fall of Deathwing. They are introduced in 5.4 on the Timeless Isle as a faction that is 'investigating' the Isle. A few of the characters from the TCG are there on the Isle. However, they are also introduced there as having different titles, like Historian, Weaver, Warden, and Watcher. However, I took a look at the way they are presented on the Isle:
Presented as Roles
And it seems a lot more like they are presented in their dialog as a class. One, the Warden says that he is a 'staunch defender'. The Weaver says they 'repair the timeways', and the Watcher says they are like a 'scout'. You have a tank, a healer, and a dps role right there. Could you make a class out the Timewalkers? What would they do? They seem to be an arcane faction, relying on temporal magic, as the Weaver is wearing the mage armor tier from Dragon Soul... And the Warden is wearing plate armor. Would it be interesting to have a class with different specs that wear entirely different armor classes, or just a pain? Of course, studying the card set I see that the weaver is also a 'bloodmage', something that you see in WoW only in a few places, and even then, only by blood elves near the Dark Portal to Outland. Ah, but a mage nonetheless. Bianca is also a mage in the TCG. There are battlemages in WoW, and they do wear heavier armor than regular mages. It would be interesting to see a battle mage type class introduced.
The Arcane Art of Time Travel?
Already, though, the mage class is starting to get a lot more 'time' based spells, having Slow for quite some time, Alter Time, Time Warp. Obviously the control of time is an arcane magic. If there were a Timewalker class, it would be a more time-based class, probably 'rolling back people to a point of past health' or something. It would certainly be a support class, and i could see there being a lot of ranged attacks or blinking away or stopping enemies in their tracks. I see that the faction in the TCG encompasses a lot of classes, actually, there are Timewalker druids, Lightsworn, etc. But I would assume that the actual travelling in time is done by mages and some form of arcane magic. This is odd, as that would be the realm of the Kirin Tor and the Blue Dragonflight... so the Timewalkers has to be something completely different than mages... or there is some overlap into the arcane and the temporal to a degree... Most of the temporal things you see in the game are a kind of bronze or yellow color, while arcane is more purple-looking... if you go to the Caverns of Time, there's a lot of purple energy just swirling around the place... It would be interesting to see more of the time travel element in WoW, more paths to travel in in the Caverns of Time...
An Expansion?
Now, also, keep in mind that most classes relate in some way to the expansion that they are in. Death knights made sense in Wrath because we were fighting the Lich King. Monks made sense because they are related a lot of the lore of the Pandaren. What kind of an expansion would there be for us to have time-traveling mages? Some kind of Time Travelling expansion? Obviously, you would have the freedom to explore the many possibilities of WoW, the past, the future, alternate presents... that would be kind of interesting, you travel to the past, to some important event, you change something, and the whole world is phased differently to you, as you have altered something, but that alteration lets you get to some new thing... that would make for an interesting expansion, especially to the people who are always clamoring for 'bring back vanilla servers'. Maybe with a time travel expansion you could offer such options to players? Of course, I suppose you would have to ask who the villain of such an expansion would be, I would guess Murozond? Or some other thing that corrupts the Bronze Dragonflight, or some paradoxical event that as a Timewalker, and with the help of the Timewalkers, you are to defeat. It would certainly be a change from the typical, "here's some new places to explore" expansions of the game.
Do I think they will actually DO this though? Maybe not in the next expansion. Maybe not ever. But it's nice to dream... What do you think? If they were a class, what kind of abilities do you think they would have? Or what kind of things would you want to see in a time travel expansion? A futuristic Azeroth? Events in history that have not yet been explored by the Caverns of Time? What would you change in the world?
