boxing ring for mma

what are your opinions on holding mma events in boxing rings? I've noticed some promotors on here with events in rings and was wondering what fighters and spectators thought about this?
No big deal, or yeah...you'd rather it be in a cage?

 Fighting-wise, the cage is better. No worry of restarts from fighters getting tangled in or near the ropes. For fans, the ring might be better because it's easier to see.

all around a cage is better for MMA, Safety no doubt. as for fans seeing a cage is just as good. if not better too see.
