Not really centered around it, but I used to use the Druid in my old timebow:
52n 5rp 5rp 5rp 5rp 5rp 5rp 6qq 6qq 6qq 6qq 6qq 6qq 6qq 6qq 6qq 6qq 6qq 6qq 6qq 6qq 6qq 6u6 6u8 71b 74b 74b 77c 77i 7am 7am 7do 7do 7n3 7q5 7q5 7q5 7q5 7q8 80d 80h 80h 80i
Probably would be better with faster healing and some other changes. Anyway, I dont use it anymore, the FGs later added were almost all bad match ups. The ones you can consider good match ups are: Chaos Lord, Destiny, Elidnis, Ferox, Fire Queen, Gemini, Incarnate, Miracle, Neptune, Paradox. Havent really tested vs FGs added in 1.27, but I feel there would be no good match up there.
