Just a warning for WW:
Please try EXPERT Ringing Bloom on Free Lives before you attempt it in a Multi-live.
It is a 28. I repeat, it is a 28. In fact, it's a HARD 28.
In my opinion, it gets close to a 29, and I'd rank it as one of the top 3 in difficulty, along with Roku Chounen... (WW's only 29) and Re:birth Day. Thanks, Roselia. XD
I'm writing this because when Ringing Bloom showed up for the first time in a multi-live, I picked Expert habitually (those aforementioned songs and the honorary mention Maware Setsu... are the only songs I can't comfortably play on EX), but noticed that everyone else picked Hard, so I changed to hard. Honestly, hard is at the level of a normal EX already, so don't be ashamed (you should never be ashamed to pick an easier difficulty) to pick it.
I beat Ringing Bloom on EX in a free trial, but my event team has 300 life recovery Ako and Sayo. I would like to remind you guys/y'all that in a multi-live, you could end up with all scorers, so even if you can beat Ringing Bloom on EX, make sure you can do it consistently and without healers before you choose it in a multi-live. I plan on picking hard because, although I replayed it and survived much more, I could die at any time.
In short, try out EX Ringing Bloom in Free Lives before you pick EX in Multi-lives. Make sure you can consistently clear it without healers.
