What I forgot to mention, is that this ruins the whole event in a way, since there's a ton of every item already, there's not really a point to farm to mission map as it is
It's an event where you get free stuff and there are other items besides the balloon that you can get. Why complain?
These items are basically helping people that don't p2p. If you want to get end game/perfect gear, these events shouldn't bother you anyways.
