The less fun stuff of the patch 
When fighting many of the Empyrean AI, they will often use envelopment superitems that allow them to mitigate incredible amounts of damage.
With how current deathblossom works, DB won't shoot at a target it does not have a direct path from the DBing ship's firing port to the target (or line of sight, for lack of a better word) - whether it's a solar body, another hostile target, or an envelopment.
Estelles have TWO envelopment supers, Ascensions deploy drones that apply envelopments to heal targets, Celestes have envelopment supers, the Apex, Saros, and Aelia fleet bosses all use envelopments. The only Empyreal AI that don't make use of envelopments are the two capships and the two light fighters.
Because of this, there is often a time where a gunner that coordinates a Perilous Burst/Perilous Scope/Fleet Commander damage aura amp and whips out the mining beam/hermes fire maker burst will... literally shoot nothing, because every possible deathblossom target has as envelopment active and becomes an invalid DB target. It doesn't happen all the time, but when it does, it's pretty frustrating.
I don't know if this falls within the scope of Empyrean zone or DB design, and I'm not really sure how this interaction can be addressed that isn't a potentially shortsighted change, but I figured I'd at least bring this up. Bubbles are not fun for gunners in PvE D:
