3 Tiers Only but this one is actually correct

I agree that there are only 3 tiers but here are the correct ones each tier is interchangeable:


top: phi mu, ddd, adpi,kd (kd and ADPi had a couple of bad pc years with lots of snaps but they are still top tier for now)
mid: axo, dz, aopi, chio, zta, kkg (zta had a good year but they are still mid and you can stop self ranking) (axo and dz are also sought after even though people hate to admit it)
bottom: pi phi, agd, sk, dg (stop the self ranks)
