According to this tier list, Ninian's the only new unit in the banner to get an S or higher rank, so yeah I'll save 50 Orbs for next banner, and I'm not really fond of Dragons. Sucks Xander is early May.
Those 10th Stratum missions are outright murder/for wealthy people only at this point.
Honestly, I like skill inheritance. Helps keep the units I like as usable. Granted seeing Vantage everywhere will be a pain in the backside, but there's a lot of things you can do with it to make the mediocre units better. Start throwing Death Blow and Darting Blow around a lot more, start building concentrated threats, hell maybe it could even make Hana somewhat usable. Who thought that giving the squishy myrmidon Life or Death and Obstruct was a good idea?
Also, it's not going to be some huge screw-you to the F2P people because they can't keep competitive, it's going to mean that whales are going to end up in the arena against other whales and F2Ps are more likely to be fighting other F2Ps, which is honestly probably better for the players.
Literally any unit in the game likes Darting Blow. Especially Sanaki as iirc her Spd is a bit lacking. Other than that, she lacks a purple and a B. Given her squishyness, I'd personally put the purple as something like Noontime or Reprisal. Maybe Moonbow if you think it'll help, but imo Moonbow and co. are much better with physical weapons than they are with magic. As for the B skill, the obvious one is Vantage, although I suppose Seal Atk could be handy if she's not getting OTKOs.
And I for one don't mind them giving us lots of free orbs. Especially now that there's a better use for duplicate 3*s, we can always use more...
