Only balloon that was useful as Kazu said was the one that gave the highest exp boost (cherry blossom). The others were completely useless. The buffs on the other balloons were...just terrible. I looked up the buff chart on IAH's site to see if there were any actual good buffs. 30% gold increase? I'm going to assume the gold increase would be from the abundant COPPERS that drop from monsters. 30% of a couple of coppers really isn't that much if you think about it. It might've made a difference if the bombs in f7 were fixed and actually dropped stuff but currently, nope, still useless.
At first when I heard about this event, I was excited because I thought maybe just MAYBE.. the trip/laptop/mp3/etc balloons were going to be given out so that everyone would be on equal ground. I saved up all my vouchers (about 25?) in hopes that a USEFUL balloon would be added. Alas, it was only a dream..
. The balloon event is coming to an end and so, the other day I was forced to decide what to do with my vouchers
1) Leave them in my inventory and hope they work for a future event for future items that are better (pfft)
2) Buy all of the balloons just so they can sit in my inventory and be useless
3) Choose between a) useless balloon
useless balloon c) useless balloon but cute d) exp balloon - semi useful for leveling
hmm still 20 vouchers left....buy more cherry blossom balloons?
And for the record, yes everyone I know including me, just logged on and afked for the voucher and signed off...or afked some more.
