This is a post that will try and be comprehensive as possible listing every bug currently with dracthyr regarding the additional classes the race received. I will start with a bug report that I recently sent:
Dracthyr in dracthyr form have no sound effects for certain abilities. This is noticeable when you compare activating an ability in visage vs dragon form. Abilities include several from warrior including mortal strike, execute, rampage, impending victory (unsure for victory rush base), raging blow, onslaught, slam(dual wielding)/hamstring(dual wielding), demolish (partially and varying on spec), and revenge. I am certain these sounds are tied to the animations too as other classes are affected.
(Note that pummel is said to be affected too so note for Blizzard here to take)
In my report, I mainly spoke of warrior. I am certain however the issue is tied to select animations as there are a couple animations for dracthyr in dragon form where the sounds play correctly. It can also explain why the sound issues is wide spread to all melee classes when you can find abilities that do work versus ones that do not.
Now besides lack of ability sounds, lets move on to emotes which is much more simple. They absolutely do not work in dragon form for NON-evoker classes. Meaning no sound for ANY of them. I hear too that no dialogue including error quips work. Even weirder, people say if there is dialogue it’s in the male voice. I play as male characters so I’d have never catch that, but I want to make sure everything is here.
Please post anything else I might have missed or insight. Until this is fixed, will bump this thread weekly and edit in anything I missed that is brought up.
TLDR
Dracthyr in dragon form are missing:
A. Sounds for select abilities (mainly the impact of weapon against target)
B. Sounds emotes (ALL)
C. Voicelines don’t play when using a mount to fly and using Aerial Halt. (Caught by Lunae!)
Incorrect sounds:
A. Male voice for female on the rare occasion it is heard
B. Pandaren voice for one of the dracthyr charge voice lines (Thank you Battlecruisr!)
C. A female dracthyr triggers the male grunting voiceline on every cast of Aerial Halt (either / version of it) when using Soar at max cruising speed. (Also Lunae, thanks!)
