why did 1/3 of gphi drop

Ur obsessed

It's because GPhi had a lot of internal drama going on. The sorority is very split. Half of the girls are relatively chill, and not super involved with much at all, and have friends in all kinds of different frats/srats, while the other half of girls are the hardasses.

GPhi isn't allowed to have any events with non-ifc frats, which has caused a lot of issues for them internally, since they (the hardass half) wanted to rise in the ranks like kappa delta, and go to better parties, however, they couldn't, since the lots of the middle frats are unaffiliated.

So GPhi is basically perpetually stuck as bottom tier, unless DTD starts mixing with them again (Which they won't)

But that's what gphi wants. Why do you think they were the cause of the zeta ban?
