legitimate fraternity rankings

Every one of those adjustments is wrong. Independent of other issues (which do still exist btw), DTD had a mediocre rush and ADPhi had a terrible one, and this is still hurting both of them. AEPi got some surprisingly cool kids and SNu's wasn't as bad as people are saying. They lost some kids they wanted to KA and DSig, but they didn't have to take any kids that are actually bad, unlike ADPhi. PiKapp's rush was fine, but there's no way they're above Pike. Still very limited key 3 and they mix with plenty of lower-mid sororities. Closer to ATO/SigEp than Pike in my opinion.

DTD's pledge class is not a strong one. They got a lot of kids, but most of those kids went with DTD because they weren't given bids elsewhere. As opposed to SigEp, which had a large class and earned that large class by luring kids away from other fraternities like Pike, ATO, and even one from Dsig. The general consensus is that AEPi had a very strong pledge class, even with just 23 kids (I believe 8 fewer than DTD.) I don't think AEPi took any duds the way that DTD did.

The commenter above knows what he's talking about. Sig Ep has clearly moved a tier ahead of DTD and AEPi has taken Sig Ep's spot

I don't think they had to give out that snap bid, though. They already had 22 in their class. I think they just wanted to add that kid to their pledge class, doesn't seem to be out of necessity.
