Hello! I've recently returned to the game and used the Flying High event rewards to start leveling arcanas. My first was Dark Diviner, because I've mostly been using magic and I heard it's a good choice, but after leveling it to 50 I'm not sure if I understand it yet. The downtime between Thunderblight expiring and the end of its cooldown doesn't feel good, Shadow Flare and Polar Vortex feel too slow to charge and their AOEs seem too small, and it looks like the arcana doesn't do much for regular magic until link 9 where an extra 2 levels of intermediate/fusion bolt chain casting are added.
I'm about to unlock my second arcana, Alchemical Sharpshooter, and I think I'd like to main it instead of Dark Diviner, after trying it in the arcana trial. Is it fine as a human or should only elves consider it? I also still have the crest selection boxes from the Flying High event for leveling Dark Diviner to 50, should I save them to raise Alchemical Sharpshooter to link 10?
