Anyone on the JP side had any experience with Uevo Neptune dragon and Meri? I realize that it takes a lot more orbs to get to max multiplier, but that HP buff sounds desirable.
PadX's team simulator told me that, even will max level +297 team members and the +15 % hp badge, I won't be able to break 30k hp with Meri/Gabriel/B.Meta/S.Urd/Sitri. I will, however, be able to heal like 21k with a heart match of three.
it's really really really good. Biggest issues as you noted is orb production. My JP box is super limited so I don't have any of the major players for water teams but I'm still able to clear out a silly amount of content by just stalling for Meri and Hatsume. I've even survived 10 turn skill binds (before tamas cost 5 freaking coins) with unawoken teams.
Really if you can consistently pump out orbs on the floors you can't stall on this combo is really hard to take down.
