SCP-914 upgrades going off your original loadout

Currently, as it stands, the way 914 is abysmal. Lately, I’ve been trying to figure out the tech tree of 914 to graph it out into a fun little line graph. Still, after testing, I’ve come to realize that the reason all the tests end up in major confusion is that the items the Class-Ds were given aren’t the items being upgraded, it was their original load out.

914 as it currently stands is not in a good state, it focuses as a direct upgrade to Class-Ds and is practically pointless for tests.

All I wish for is 914 to upgrade depending on what you currently have in your inventory, not with what you spawn in with.
