People who've clearly never played white mage should probably not make suggestions on how to play the job. Medica II is a good idea, yes. But whms do not dps after bees spawn. Dps before first KB, yes. DPS before 2nd KB, yes. But once bees spawn there's no more dps. It is keeping medica 2 up, keeping regen up on everyone, esuna the derps/lazymelee, and Cure I/II whichever dps has aggro on the bee that isn't being tanked.
