I'm sure if you've been on Manacube for a semi-decent amount of time you've seen your fair share of shouts along the lines of: "Cubit cf /skyblock" , "all in cf /whatever" , " cf meee" etc. My suggestion is to make cubit coinflips global. This making it easier and faster for the cubit coin flippers themselves, stops a lot of annoying shouts that players are forced to see and generally seems like a pretty good idea. Of course there will still be coinflips realm-locked with in-game cash/mana, though there's no need to advertise these cf's via /shout.
With global cubit coinflips (could even be implemented into normal cf's) you could toggle on/off a chat (id recommend its base setting to be off) allowing you to choose if you want to see others coinflip outcomes (I'm assuming most wouldn't/really don't care).
This would help to reduce the ever-growing unstoppable spammy pollution the average Manacube player sees in their chat *cough cough* "Apply for staff" "Limited time crate is out" etc...
Please comment your thoughts and anything you would like to add.
PS: Yes, I know ironically I'm one of these annoying ass shouters that advertises cubit coinflips, <3. +1 this and hopefully we can change it : )))
