What is RUMBLE?
This is one of two minor league promotions under the FIGHT! MMA banner and is based out of the American Southeast in Florida and Georgia. RUMBLE being a minor league does not have as good of payouts, hype, or even coverage as FIGHT! MMA, but is slightly better than SLUGFEST. Aside from that it's pretty much what you would expect from a small to mid-range company (think WEC).
Weight Classes
RUMBLE focuses on the 205 to 155 divisions.
Championships
RUMBLE will eventually have a title for every weight class.
Territory
To begin RUMBLE will promote out of Florida and Georgia before gradually branching out to nearby Mid-Atlantic and Gulf states.
Anything Else?
RUMBLE is setup the exact same as FIGHT! MMA to avoid any confusion. Same app, same point scale, same sim, everything, although the results may well be lesser (it is a minor league afterall hah).
