OK, I was just wondering what was going on with this. Yesterday, I was working on leveling AST. I had leveled to 73 all through Frontlines, but yesterday I decided to try some dungeons. So, I was quite confused when EVEN IN BATTLE the cards being used on the DPS weren't generating the solar/lunar/celestial seals. I realized it wasn't until I actually used Combust on an enemy and then used a card that I got a seal, which is astronomically ridiculous.
Oh yeah, and Celestial Opposition is a joke now and Divination's CD is WAY too long for what it does.
