I really hope they will still make the Draenei male chintacles 3D and perhaps add more polygons.. We've seen that it can be done in numerous official in-game cinematics so I seriously doubt its not possible for the devs to implement this. Also I doubt that the polycount would increase too much, because if I look at some of the other hairstyles like the Dwarf beards they seem to have a lot more than 3D chintacles would have.
Honestly I wouldn't care if the metal parts get bent during animation.. I find that less of a deal breaker than them looking to be painted on there.
Also I was wondering why they can't make a geoset where the chintacle attaches to the the face similar to how the horns of the Taurens seem to protrude out of their skull. Instead of you know.. having the metal come out of their face when it is not portrayed like that in any artwork at all.
On a side note some of the facial hair looks really bad model wise and parts texture wise as well. Some of the textures have too much level of detail compared to the rest of the hair textures which breaks the cohesiveness a little bit.
So here's to asking the devs to get them in before 6.0 hits the live servers.
