I do not support 6, because PvE gear is the best gear in the game (for World PvP and for PvE that is) and i feel like PvE gear should be rewarding. Of course it will affect PvP, even tho you lose PvP Power, when you're low gear and you buy PvE gear (some off pieces and such) you stoop around 45 ilvl's ahead (even tho you lose a bit of PvP Power) this could benefit alot, and if anyone gets Free HC gear, PvE would become more of a joke than it already is.
Keep in mind that this might be a biased statement since i do raiding on 100x myself (even tho i know you're talking about Fun).

The only thing i think they should add, is make Fun realm a real Fun realm, so either insta Full Grievous (or Prideful) so you do not have to participate in the endless cheater filled battleground grind. Gearing up alts already takes years due to Cross Server crashes and hackers of opposite (and on the same) factions.
I think we have leveling realms for a reason (being PvE and actual character progression, even if you reach level cap in 3 hours) and why it's called a Fun realm for a reason.
Another one is host RBG tournaments (and if ANYONE dares to cheat in those tournaments they get 30 day ban or disqualified, and the opposite team wins be default), i know not alot of people enjoy Rated BG's here but it can actually be alot of fun if you have a proper group, + it's not the same mindless play of setup after setup after setup and bam win eventually (take WoD RMD as an example), considering you have to for an example cap nodes, defend/cap flags, strategize properly. RBG is alot more intense than arena's if you play with a good team on Teamspeak vs another good team.
