Is it any surprise as to what I'm going to suggest?
Gladiator Duel Mode (I'm tired of people shooting me when I get a streak or when they are losing)
Gladiator Clan War Mode
Room options to limit equips, disable flip, and also the ability for the room master to kick anyone whenever they want, and the option to do the same thing in clan channels. Also lets bring back that thing where you can look up a character name and see all the other characters they have on that account, because I'm tired of all these dumb alts. And maybe a gladiator server. Also training swords and swords that are less than 15 dmg. I'm tired of every new sword just being stronger than the last, start making weaker weapons. Only exceptions would be the wooden sword and the goblin commander club. Maybe some gladiator events too, but they're not going to be up on current gladiator and would probably have stupid rules where elements and any equips are allowed and they'd make it played on stairway or some stupid sht like that.
