1. Grouping tools to make forming groups for group based content easier.
2. AFK flags to show your afk.
3. 8-man( raids) end game content, so there is some other end game content besides PVP.
4. Additional way to lvl pets without having to grind the pet games (maybe allow pet snacks to be feed after PVE battles, yes it would be slower to lvl but then I can chose to not play the pet games).
5. Have double EXP, or increased drop rates on rare items weekends.
