i think everybody hate the fu forge system but most of all you cant give over heat anymore to players + most be in a arsenal or town
so made so we can forge anywhere because every time you heat in fsc you need to go up and all you pills and remedy and vita will be gone.
n made a arena that infinite and see how long you can survive without rev and there the old rev system are or just you have a limit of spark of life
every 10 rounds you get full health
but the arena gets harder and harder.
and a special reward or just a other Colosseum game maybe. or least 100 rounds maybe and a reward if you survive them all kind of reminds me of pokemon colosseum.
or maybe gonna take back the Colosseum hat thing as reward super brawl crown

including the bosses and multiply of vana for example
the forge was meant to make people stop grinding bosses. so, stop grinding bosses.
infinite arena? already suggested, better and with more detail. search for "how fezhor would design the core", and "storiline additions: the reaction" for two examples. scroll to bottom on the second.
there is already a bring back SB thread here somewhere. it was removed due to weapon imbalance, so it should have predetermined weapons.
