So I think daily orbs may be gone for good. Which has lead me to reconsider unit building a little bit.
Ive 4*ed Alfonse and Anna as a result, since they seem to be common quest completion and arena units. I have also looked at some of the more intensive monthly or event quests for additional orbs, because that seems to be the approach IS wants us to follow by leveling up the required 3* units.
Doing Barst and Hana right now, as I believe this isn't the first time they have been required for quest completions. Is there a rhyme for these selections that anyone has discerned, or is IS just picking units at random and saying "Kill lvl 35+ foes with Matthew/Arthur/Wrys" for fun?
