well, i have to go with the old guard here.
I find E, F, J still more logical.
imho the long explanation helps. totally not confusing.
A is reserved for Alien implants, which are not available.
B is reserved for Bumblebee and Betelgeuse Implants, which are all defective, and were recalled. Also I feel like a Sofa and can’t transform, after using these.
C is reserved for Centaari Republic. Don’t trifle with the Centaari. Viiiir! It is now forbidden since it partially is shadow tech. It all will end in fire.
D is reserved for the Dominion, a failed attempt to open a wormhole into the delta quadrant however made them redundant.
also it is said, the dominion lost the war. omg did i just spoil you? btw. it’s the gamma quadrant. my mistake.
E is empire
F is federation
G was for Guard-Implants, but Jericho bought them from Rakza.
H and I implants (hybrid and introspective) are devel only implants. I also is generally confusable with implant itself. Or me. Or u.
J is the new G. Jericho.
O Implants are generally o so hallowed.
S is for sweetroll enhancements.
i don’t mind rly, i would understand both, since after this list, as we can see, a-c are clearly unused. but i think, e, f, j are still more clear, the 3 logos are still there, and it helps, if people get a little bit into the spirit of the background story and the factions.
