Gamabunta isn't a new feature lol it's only a little add (showed in 3.0) to an old feature that is Group Summon.
Kick Gamabunta's ass instead of Serpent is not somethings new, mostly if more of us do it in auto, and just for say, summon chakra are the same.
For explain, one time that you have captured Gamabunta, you can easily call Serpent back by helping the low power player in your group to get 40 coupons. Cause, like i said, one time that you have captured Gamabunta, you c*e the same summon chakra dropped from Serpent to upgrade also Gamabunta, so wow, new feature last for 2 days, cause this is the time that an 350 activity rate group can capture the froggy boss xD

I'm only happy with that new event, cause i'm close to get the Gnw super rare and i don't need to wait more weeks. Glad to see new weekly event, but nop, Gamabunta is not a new feature. Do not make fun of ppl that pay yours rent, is not cool. xD
I say it with all the calm of the world and without makes argument.
