I believe its time for another promotional CE buying tool:
-Pet snipes along with your CE purchase?
-semi permanent mecha knight token? (kinda like a raise a pokemon deal, or even a merc-thing )

Guild-only quests, perks, and rewards:
have "fetch" or "kill this" quests for guild hall trinket decorations!
special completed guild hall rooms build "cheaper costing" alchemy boards (HOWS THAT to WANT to join a guild?)

Arena type matches for Mecha knights and monsters?
-causes lots of yelling and betting!

Leader Boards for Guilds

More elemental types of enemies (fire jellies, frost healers)
more elemental types of mecha knights pets?

And more info on the final lvl.. I've been there... I want the "FINAL" quest... like a core raid or something.

------------ if these ideas were already said... then I simply want to add to the mix then!
