I traded my RBG for one with some other items... its noticeably faster. I have always heard RBB is faster but tried a RBB on as well, i think they both sit at 30% and RBG is 26-27ish.
As for the frogs, they have well over 5k. It would take me forever to solo one. And thats with SBC/Lam/Frostbringer.
