I do as many as I can at once. I'll run Mistral's "Cave of Flames" second dungeon, "Wielder of Fire" multiple times when I'm not trying to do event dungeons or parades. For 3 energy, you can get up to 5 offensive brave burst fodder, as well as little XP which is easier to manage for me - I don't like getting large chunks of XP - I like to control my Energy refresh at level up.

So when my unit inventory is full, I'll go fuse 5 at a time, or whatever's leftover, into the unit I'm trying to raise the BB Level of.

I start at level 1, where it's cheaper. You'll have thousands in the long run, but saving a couple 10K is just a drop in the bucket compared to the millions you'll be spending in the long run, so it's up to you whether you want to focus on BB levels early (and play with low level units like me), or at later levels (which cost more, but you have stronger units to do quests/dungeons with).

There's no solid proof of this, but I find the chances of fusing one or 5 units at once the same. I've gotten 3 BB Levels at once from fusing 5 units, and I've gotten 2 BB Levels with 2 units.

So while it seems I'm leveling BB "faster", I'm just focusing on BB levels by fusing more low level fodder at earlier levels. I'm not going for unit levels, because they add 100 Zel per unit per level. My level 20s with BB Level 8+ probably have been fed thousands of Burnies!
