ranking explained- bottom tier

Ranking is relative, thats why these ranking posts are all over the place. Basically, it depends on what type of girl you prefer, and obviously not all girls in one sorority are the same. Why are sororities ranked? Based on money, exclusivity, and loosely based on looks (not necessarily personality or type of appearance).
Bottom Tier- These three houses have girls that either had a terrible rush, are a snap bid, or really arent meant to be in a sorority at all. Sorted by relevance
1. ADPi
Why? Aren't social, not usually that pretty, and didnt want to drop because of the sisterhood or being in a sorority. They are genuinely nice girls and there are a couple of really great girls in the batch.
(Way Below ADPi)
2. AXiD
Why? These girls are a random mix of people, most of which aren't really sorority material. Some just had a terrible rush and did not want to drop and be a GDI. There are one or two ok ones.
(Waaaaay Below AXiD)
3.SDT
Why? They don't even have a house. I'm pretty sure they don't have mixers, and its painful to go through rush and see their house. I don't doubt they have nice and smart girls, but these girls are not sorority girls and this is not a sorority at all.
