Yes there could be other experiments, but they wont be drakthyrs lol.
Draconids the melee dragons, arent drakthyrs either.
Drakthyr is purely the aspects powered ones lol, if another experiment of melee draconids come out the woodwork.
They notably cannot be drakthyr.
BecUse they dont fit the exact definition set in lore for us which seperates us from the other dragon based races.
There is more lore to give evokers a melee tank specc currently then to add a class to the race.
Also no.
He couldnt do better, cause the gauntlet that offered him the power broke during OUR creation, he lost the ability to make dracthyrs after us.
That is why he turned to the void.
He canonically was corrupted to void after our creation and he couldnt confirm able to control us.
So no canonically, we were the last steps. Also canonical that we are the only experiments he didnt destroy.
Watch belluara video on the latest deathwing lore release, u will find it all there, this concept is in current lore seriously cut off it would require retconning several factors and likely delaying the break of his gauntlet + turning void in his time line to fit another experiment into his schemes
We know he stripped a ton of power out the aspects back in cata, we pressumed to stop the other aspects ending him, yet drakthyrs are the real reason.
He used said power to experiment with half dragons. Using a titanic gauntlet to control us, once the gauntlet broke, he couldnt confirm stability of his control so he froze us and turned to the void.
True they have, but dont u consider the fact the followed that statement upto that was launching not only a class that can play one race but also a race that could only be one class abit weird?
You could be right, they may add extra classes, it is defintly a possibility. But there will most defintly be retcons to put it in place.
We know drakthyr wont get extra classes this expansion, however its not ruled out for future expansions as blizzard said, id just find it sad if drakthyr gets opened up before DH does.
Theyve waited 6 years longer then us.
Espically as the outcry for DH is far larger then Evoker.
They may in 11.0 drop every class onto drakthyr. Is is sheer possibility and i suspose theu ignore plenty of high power sources for the sake of it plenty anyway.
Depending on the outcry for it ofcourse.
