For a general Rdruid healing set I'd say just get haste BoA, maybe fallen apprentice robes. Enchant for SP on gloves / bracers, minor speed boots, haste on neck / rings / cape up to 25% + wouldn't go over 30% and Vers after that. Vellum Ripper gloves / Cuffs of the Black Elements from RFC or MTB if you can get, 1 int vs. 2 stam though so nbd. GMB is nice but spirit is important in bg's. Try to stay around 5k+ HP and 25% + haste, rest is pretty straightforward.
+16 SP Weapon enchant and maybe swap for heartsong in BG's when you're getting low on mana.
