It is hard for me to get a solid opinion on “leaks” in general since it helps to actually see what is mentioned in action. That and a lot of “leaks” are usually wrong, though they seem to get the general theme right at least.
I suppose I can give my opinion on that Black Dragon race from the “leak,” though I will stress it is my personal opinion and that it may not be what exactly happens.
Assuming we take it as face value, it seems very lackluster since it sounds like we’d be running around and doing stuff in combat as a humanoid form, consisting of already playable races. It doesn’t sound like we’d be in a dragon form, other than a racial attack, likely lasting a few seconds, or as a mount form. Assuming that is how it works, it is a bit disappointing to see all the playable races tossed into one particular race and called a new race.
Granted, I wouldn’t expect to be running around questing and in combat as a dragon all the time, cool as that actually does sound. I can think of a number of issues with the size that the dragons are suppose to be along with the shape of their body. It’s just that for something like a dragon aspect, to see the humanoid form take up the majority of the action while the dragon form takes a backseat, it just doesn’t interest me as much.
There is also the idea of any of the Dragonflights siding with the Horde or Alliance, which I see issues with it in the long term. What happens in the future if there is yet another faction kerfuffle? Why would any of the Dragonflights want to join either faction when their group has a greater purpose to deal with? Likely, there are other issues I can think of as well. The idea just strikes me odd.
That is what comes to mind so far. This isn’t to say I’m completely against the idea. As I said, if this is true, I’d need to see it in action to be able to give better judgement. The idea does remind me of another MMORPG with Dragons as a playable race. You started off as a whelp, and it was a long and arduous journey to become a fully grown dragon.
Anyway, if this does become true, I’m not really against the idea. I just need to see it in action to give a better opinion, assuming this is what we’re getting in the future. I’ll make one just fine and see the storylines of them. I don’t think it would affect the MU Stonemaul Clan at all, since even if it were Black Dragonflight members specifically, they wouldn’t be evil ones. It would likely just take gathering the MU Stonemaul Clan and explaining through meetings, drawings, powerpoint presentations, hand puppets, and lots of kegs of ale to get them to know they’re allies and not the ones who wronged them.
In the meantime, I’ll keep an open mind for now until we see what all comes with the next expansion.
To be honest, I usually view dragons as a separate creature than reptilian races. It’s a bit hard to explain, since dragons are big reptiles, but there is a different look, feel, and overall culture between them. As a result, I gravitate more towards Lizardmen than I do with something like Dragonborn from D&D.
So for me, it wouldn’t satiate my yearning for reptilian races on the character creation screen, though I’m not opposed to them of course. I think having both Sethrak and Saurok playable would make me perfectly happy in that regard, since they’re both reptilian and would be different enough to have them be playable and different experiences.
If we go by what Blizzard has said before, they plan usually two expansions ahead of the current one. So when BfA happened and all the race request megathreads popped up, it’s possible that we could start seeing that the expansion after next. Granted, some could still pop up somewhere during an expansion and become playable then, so who knows?
I do hope we see requested races gradually added to the game. WoW in general has been in a less than ideal state for several reasons, and while I don’t think new playable races are THE solution to all the problems, I think it is one solution that would go a long way in helping to keep people happy and attracting others to the game. To see player requests in general, within reason of course, being granted long-term would be good in many ways.
All we can really do is keep at it and see where the game goes. As I said, as long as I still play and enjoy the game, I’ll keep going with support for the races I want to see playable.
Dream big, Ogre fans!
