Fake rivalries

I saw some people saying Gen.G/PRX isn't a rivalry because Gen.G always win (Gen.G 9-5) but PRX's record vs Gen.G is a lot better than some other teams:

FNC vs VIT (FNC 9-0)
G2 vs NRG (G2 6-0)
SEN vs 100T (SEN 15-5)
LEV vs KRU (LEV 13-7)
KRX vs T1 (KRX 8-2)

The sen 100t rivalry has some ground now that the former sucks and the latter doesn't

Same with lev kru

100T vs EG (100T 9-0)
