Spammer or whatever above aside, I’m still in favor of this only if it’s for shrap. I seem to recall a premature VU notes said they were adding that too, but maybe it was only intended as shrap to crafting loot. UA is meant to be bound for TT in for that account though, which doesn’t really match what residue is used for (residue is only consumed on a success with no TT loss or profit tied to the residue).
Before residue prices went up, they were hanging around 100.5 to 101%, which would ballpark to the current shrapnel conversion. That would help keep prices down too, especially as it seems there are fewer EP4 crafters feeding the residue need. For most component crafting, a return to 101% sure wouldn’t significantly affect my crafting returns either.
Basically, it seems like shrapnel is already set up well to be a universal residue given how the alternative conversion to UA is set up.
