So as I'm logging around my level 100 toons today, when I got to my shaman, I suddenly realized I didn't know if she was going to have a spec that she could transmog into Gorehowl with the artifact weapons. I don't play enhancement, and I remembered that elemental is getting a fist weapon (cool enough), but... Gorehowl?
Not all of my toons have weapon transmogs that I care about; my mage, for example, has the basic Draenor staff because all the staffs I like to go with her transmog are bound to other characters, and at this point I'm not buying duplicates when the looks are going to get shared so soon.
Some of them, though, I'm probably going to have to change.
Hunter (main), marksman
Currently: Golden Bow of Quel'Thalas
Changing?: Nope, hunters have been able to transmog between ranged weapon looks for a while, and Marksman is getting the bow artifact, anyway. The Windrunners are cool, and all, but I'm a Tauren. My alt hunters by and large don't really have a preferred mog weapon, although my original Night Elf is tranmogged into the Gorewood Bow (Blightcaller raids, heh) right now; most of them may use the artifact looks.
Warrior, protection/sometimes fury
Currently: Blazing Rapier/Drillborer Disk
Changing?: This pair was picked to go with her current transmog, so it really depends what pops up in the plate transmog, as well as my one-hand/shield options. I did pick up the sweet shield Naana has paired with Quel'Delar, so I may look at the blue/steel/yellow/gold options. That said, the base artifact look for prot doesn't jump out and grab me for the kind of transmogs I like for my warrior, so I probably won't be using that unless digging into the plate backlog turns up something I like with it.
Currently: Communal Staff
Changing?: Probably not, at least not for the initial discipline staff's look. I love the bits of disc priest artifact story I've heard, so I'm really looking forward to seeing how the quest story plays out, but my priest's current overall transmog is the one I'm most fond of, and I'm not likely to break it up for a while (unless I find shoulders I like better; the ones I have currently are because they're the best color match I had available; I'm not sold on the fiddly bits sticking out of them).
Currently: Soul Harvester
Changing?: Eh... the destro staff looks cool, but... Soul Harvester. That said, I do have a lot of neat purple-colored cloth if I haven't vendored too much of it, so I'll probably see what it looks like on the goblin once before deciding for sure. Thematically, the Scepter of Sargaras isn't really a step down. If I don't like the way any of the purple looks, I'll stick with my tier 1/Soul Harvester setup.
Changing?: Unfortunately it looks like I'm switching off of Gorehowl once I get an artifact for the shaman; I'm looking at either a mace and shield or fist and shield. I have been accumulating something of a shield collection, so I'll see what options I've got to go with her current mog (which, at this point, is something of an iconic shaman look to me). I'm leaning towards elemental at the moment, but if resto solos okay, I tend to play my healing capable toons as healers (excluding the paladin).
Currently: Knight's War Hammer & Emerald Shield
Changing?: Like my other plate wearers, whether she keeps her setup depends what turns up in the plate transmog. I love emerald plate on my paladin, and the prot paladin artifact's basic look is more blue/silver than green/gold. If something turns up in the plate transmog I like as well, I might try it out. The Knight's War Hammer and Emerald Shield work with this set so well, especially using the Ripped Sandstorm Cloak heirloom with it.
Death Knight, blood
Currently: Darkened Broadsword
Changing?: As much as I love this sword (I shamelessly rolled need on it while leveling her through Outland since my troll's was bound to her (Titan Grip!)), it depends what pops up in red/silver plate transmog options. Being a green cow, I'm not sure the red/silver will look great on her. Some of the salvage yard swords for death knights were pretty cool, too, so I may go with the black/blue transmog options, again, depending what pops up in my plate options on Tuesday.
Currently: Aspirant's Staff of Harmony
Changing?: Not immediately - I don't dislike the Mistweaver staff, but it doesn't look like it goes as well as I'd like with the Wolf Rider's getup I've got my monk in. If there's a leather set that turns up in my mog interface that I like with the artifact staff, I might use it instead. This staff was picked more because it worked the best with Wolf Rider's of my available options. Wolf Rider's was picked partly so I had a toon that didn't clash with the Ruby Panther.
Don't care/waiting to see what pops up in the new transmog interface: rogue (subtlety), hunters 2-4 (all marksman), mage (frost), druid (primarily restoration but sometimes balance), priest 2 (discipline). I mean, I've got the Christmas Tree daggers for my rogue, but I'm not particularly tied to them. If I can ever transmog the Dark Herring, though, that's hands-down what my rogue is going to be using. And the Scythe of Elune! I may have to play balance more on my druid, because I love the Scythe of Elune. I was terribly frustrated in Vanilla when I found both halves of that story line in quest chains (first in Duskwood, then in Ashenvale), and they never linked up until Cataclysm and the Gilneans came in as a faction.
All in all, I think the Golden Bow of Quel'Thalas, and the Communal Staff are the two weapons I'll be keeping for sure; a lot of the others are dependent on keeping the transmog they're currently part of. I'd keep Gorehowl if I could (partly because I find the idea of healing while wielding it amusing), but alas, there are no two-handed shaman artifacts.
Bonus Transmog Discussion: Axeclaw Mail
I'm using the Axeclaw set (the Tanaan token drops) on my main for the bulk of her set right now basically because the gloves sold me on the set. I love the green/white contrast and the rivets up the inside; I this may be the only armor set where the gloves were the piece that jumped out and grabbed me enough to make me want to use it. I had been using the set belt in the transmog, until I got the Girdle of the Legion General and I suddenly had 3D pouches on my belt. I'll probably mog out of this once I find a set in Legion that I like, but pouches on my belt. I'm probably keeping the belt if they don't have any as neat in Legion.
