This is actually what I was searching through the forums for was an answer to this. From what I saw it was only RFC > WC > BfD > ZF for the solo horde druid guide which isn't bad normally; but, I'm no lifing the hell out of launch so I'm not sure how easy it would be a group to do ZF at 50 as the guide suggests so was looking for alternatives.

Classic Druid Spreadsheet
I've been working on a spreadsheet for a bit to try and get as much Classic Druid information as possible together in one place. I hope this will help people and please let me know if you spot any errors or have any suggestions. This is a continuously growing document so it will have more nad more information as time goes on. https://docs.google.com/spreadsheets/d/1Y-oXmau5zcI_hRD_Kt0XnwJV80gwUBLRwqNBaLoSKBQ/edit?usp=sharing
