Will this ever happen?
Currently, rolling with a Guardian, Sentinel, Commando, Vanguard, Gunslinger, Sage, Sniper, and Marauder, I used all my slots.
I don't know how many slots World of Warcraft has, but I feel like 8 is limiting. Maybe 10, 12, or 16 slots? I mean, it couldn't hamper the server that much.
Also, cross faction guilds would be nice. Where both factions are in one guild, but cannot PVE / PVP together. Just talk, etc. Easier to see who's online, plan raids. Myself, I hate leveling Imp toons cause I can't interact with my guild.
