To be honest not a lot of people wants 4.0 xD

as a f2p what event should i focus on? tailed beast attack or konoha great trees?

in the tailed beast attack: i'm planning to get cave keys and the rewards (number of tailed beast) is kinda good too i guess (i don't really know)

in konoha great trees: i'm planning to get the clothing (although i won't complete it this week) or cave keys

should i start building the frags for the clothing or take advantage of the cave rebate (so get the cave keys).. what would you do??

thank you
