Yes, this! I loved that bit in the Illidan novel prior to DH’s even being released, the fantasy of having certain traits or abilities or visuals reflecting the demon your character ‘ate.’ So sad that the meta forms and any other customizations they gave us had no unique demon identity. I would love to be able to customize meta and/or regular forms to reflect certain demonic aspects. I could even see a (hero) talent node for metamorphosis being like ‘aspect of the felhunter/wrathguard/shivarra/etc’ and if you take it you get a stat buff and a visual effect change to your meta.
