I have one request/suggestion I would so dearly love to see implemented.
[Mechanics]: Asthetic Demon form for HoXes! A togglable skill that morphs you into your choice of a male or female demon (potentially customizable, as HoXs were supposed to be anyway). This would be asthetics only, no bonuses to skills, stats or anything like that. To prevent it being used in PvP, simply add -%pvp invulnerabilities (like crouch, so people don't use it to hide their gear).
Could also include a Lich version for Necromancers, as Lich used to be a playable class, would be nice to see again.
As for naysayers commenting that they don't wish to see demons everywhere - you already do. Demonlogists and Necromancers running through Tarantia streets with 8 pets? HoXes/Necro's having a form will do little damage, imo. Want to RP as the demon my HoXes are.
Aside from that, main hope would be for lots of social clothing, dyes and more emotes (especially constant ones like relaxed lean, constant crossed arms, etc). =)
