Firstly thanks for the thread, I spent ages searching for Troggoth information in the previous one.
A big block of stabbas or shootas may be needed but I'm all about the DANK, so I think a Hag is almost an auto include, especially as I highly rate spell-spite.
I don't have any models purchased, so I'll be starting completely fresh so the 780 point list you posted above is extremely helpful @Malakree
