Shinsou, do you mean like when the Ixian Knights controlled most of Corone, or when Misery Business tried to take over Eiskalt?

(Amazing how a lot of these ideas are things I have done with the site at one point or another XD)

The LCC needs to return. That's one of the major tournaments that is typically good for the site.

Boss Battles also need a comeback, because Hysteria used to have some boss rewards for those things.

The Auction House. While I don't care if it's player run or staff run, it needs to return. MAde for some interesting IC interactions with people. (Just a note: I'd prefer it staff run)

Another PG war would also be good but that would require you guys get off your butts and do something about us having PGs again.

Althy League, but it needs to have a decent incentive. I think a good idea would be to not reward every fight but only specific score/criteria met ones. Dragon Ball Fighterz lets you collect the Dragon Balls after performing 7 different combo lengths, so I think having some hidden conditions known only to the judges (Did the players use some torches in a given setting to an advantage/disadvantage) gives one of the sought after pieces of the Althy league, for example.

These are a few ideas off the top of my head.
