I think in another thread someone said the animations are all emotes.

Thanks for the heads-up on this.

I bought the thing to make it (seriously, at this point I can’t remember what all of these things are called) but I’ll hold off and use my morpholith for the hippogriff mount instead.

If I have extras at the end of all the events then I can still get it.

but shouldn't the doom emote be implemented in the personality and start automatically? Like the npc's at the impressarias tent do?
for me that was the most interesting reason to get this...now i am bit disappointed.

i mean the happy-Personality also starts automatically to whistle after a while even this is another emote.

It's because this is actually an old personality based on the Breton Hero of the cinematic trailer. It had been datamined. I like it, but what bugs me about the whole thing is that instead of having an actual firewalker-themed personality as an event reward, they instead used an old asset. This reward takes a long time to get, and they had all this time to design something new. If they had just added the /doom emote animations to the personality's idle animations it would have been great, not to mention, it would have looked as advertized, which is not the case now. And they could have used the Breton Hero personality as a new reward for a future Breton-themed DLC. I still hope they might listen and rework the firewalker, but I'm not hoding my breath.
