How far into the Colosseum are you guys? I've made it to round 34 so far, which currently puts me at around 1200th place.
I want to break into the top 1000 to get the 2nd-tier rewards, but it's becoming very hard. I have to get lucky skill activations in order to succeed now, which means lots of resetting. I really wish I know how far away I am from getting there, instead of only being able to see 10 places ahead of me.
I do have to say, though... Pinocchio is actually very, very good at dealing with Gummi Flyers. He basically nullifies their damage, even at levels above 140. I don't think I could have gotten this far without him; I actually don't regret getting him from what was otherwise an awful 10-pull now.
