Jay requested something similar before,
and got lit up in the comments... by uhh... "OMG WORLD RECORD"
Removing kits from boxes seems to be the happy medium, grinders don't need to worry, and it doesn't affect people who don't need item boxes anymore.
BUT if there are any people who enjoy getting kits out of boxes, maybe because the epic kits are very, very, good and I can't see why someone wouldn't want a 144 health kit out of a box... For them, a switch. Turn on for kits in boxes, turn off for no kits in boxes. Simple as that
