a mythic bracelet whould be nice but maybe with an ability or set bonus ability instead of a proc.
If i remember correctly cinco said something like he wants to add a set bonus to bracelets that have a ability like the dragon sword for example ( spawns dmging pools/poison )
But he also said that he probaply whould have to include the ring or pendant or even both since ss are to high of some palyers) therefor he whould need to make a worth enough set bonus for ppl to be glad to stop using there ss.
Bracelts are still under development so id say we are fine with the current ones, only thing they could add should be more possibilities for ppl to get the lv 81 legendary.
