Got the Shiva and Ifrit Primal spells and did, like, two stages of the Masked Carnival. I might be inclined to try for the other achievement titles if I'm bored enough but as it stands, I'm really not motivated to even go for any completion goals regarding this thing. Not until they buff Primal spell drop rates, at least.

There are about two things that are good in BLU for me, and neither are part of the intended design or even anywhere near its original purpose and both need Self Destruct.
