From what I can tell, the new scaling is looking something like uhhhhhhh (i'm just spitballin here, feel free to correct me)
OG Timeline:
Normal fighters scale to the mountain of
9-A/
8-C feats, however they also get a
4-A/
Low 2-C/
2-C (whichever gets accepted) key for when their Armageddon Tower endings, when they have the power of Blaze
On the subject of Blaze, his profile is kinda... bad. He's Low 6-B without a calc. His power (when used by other fighters) can
create realms (Low 2-C),
creates constellations (4-A),
destroyed every realm except earthrealm (2-C),
tore every realm apart (2-C),
merges the realms (2-C), and "
shattered reality until there was nothing" (At least 2-C)
I think 2-C Blaze (and fighters with his power) is kinda obvious and consistent
Reboot Timeline:
Normal fighters once again scale to a mountain of
9-A/
High 8-C feats, probably getting a
2-C/
2-A key for their Titan selves from their MK11 ending
Guest characters... idk actually. They scale to the average Kombatant and then get a key for their Titan self? Since they get a Tower ending?
MK1:
Looking like, surprise surprise,
9-A to
8-C for the average fighter.
2-C/
2-A for the Titans and maybe a
2-C/
2-A key for the average fighter during the final battle?
