Trouble getting spells for BLU.

[Lissandra]

Also the more BLUs on the party the higher chance to learn a spell. Soloing can be discouraging most of times, and slow.

I've heard this one, and some say the number of BLUs do not matter. If anything, these are all pure speculation. Even at the rate I got the primal spells, with 4, 6 or 7 BLUs in the party, I felt I was getting them at random.

For example, I did Shiva ex with 5 other BLUs and 2 non-BLUs and it took roughly 40 runs total. I did Titan HM in a party of 6 other BLUs (1 non) and never got it. We did like 40+ runs. Then I duo'd with a friend and I was the only BLU and got it on our second attempt...
