Not sure if this has already been discussed, I haven't seen anything on it, but could a speedrun for grade 5 emissary in each of the different factions. Time could start as soon as the last player votes for the emissary and end once the notification for grade 5 reached comes up.

It sounds like a good idea as long as buying a bunch of crates to get the grade up is not allowed

yeahhhhhhhhhhhhhhh mods get on this

It's been briefly discussed with mods and dismissed. Could be reconsidered if someone wants to pop into the discord and suggest a ruleset to start with.
