Wow, Naia seems dead. Again, no Star3 rewards.
As for the event itself. Last time Star3 rewards were given out too quick - the event closed within a few minutes and no one could take any rewards, so the improvement in the rate is a good decision, but I think you've overdone it It would be good to have something in between. I could buy some tickets to increase participation rate if the XP boosts did not expire, otherwise, I will not be able to use them up, so it's a waste of adena.
PS. It would also be great if a Greater Rune Stone was Star2 and not Star3. On Naia it is sold for 17bil at the moment, which is ridiculous for learning a skill (I'm 111 and still haven't learnt my lvl 110 skill)
