And to add to that, can you honestly expect stats to only get better and better with every new event? Just because the stats aren't up to your standards doesn't mean they wont be useful to someone else.
I see that kind of attitude towards myshop as well. "Well, these stats aren't good as X set so why would I buy Y set?" Poppuri events aren't meant to be over-powered and I've never seen it that way so why whine about it?
Yeah, it's suppose to be a common goal event to get people to work together (because do we ever do that anymore?) and it's always blinded by the end prizes (which aren't bad).
