I really want Ethereals as neutral race.
Why Ethereals?
- They've got a cool story (the exile after Dimensius destroyed K'aresh and consumed their fleshy bodies leaving nothing but a nebuloid mass of energy).
- They are NOT furry, we already have many animal-like races (Tauren, Pandaren, Worgen), so getting Arakkoa would be a bit too much.
- Like Forsaken, Ethereals could show pieces of bandages or some energy through.
- They are superb engineers and could form a good trio along with gnomes and goblins (Gnomish engineering (alliance), Goblin engineering (Horde), Ethereal engineering (neutral).
- They can be a wide variety of classes.
- Their sprint animation would be quite interesting, leaving copies behind!
- They could teach Alliance & Horde how to travel through the Twisting Nether (even if Draenei already know), allowing them to eventually hop onto future Argus or whatever planet they encounter.
- Furthermore, there are already non-Consortium neutral Ethereals both in Stormwind, Orgrimmar offering their services.
And last but not least, Ethereals have already defeated Dimensius, which leaves their future unwritten and ready to suit either Horde or Alliance tastes.
