Best single class teams?

Id feel a lot better about 5 Druids if HOTs stacked like they did in TBC

could probably get fancy with some keypress down rejuv - key release up swiftmend instant heal combos. Resto/balance is good for pvp at the very least.

Do different Ranks stack? I can't remember.

Higher rank buffs overwrite lower rank ones, and you can't apply lower rank while higher rank is on the target, so no stacking in classic

was thinking more so
keypress down = druid1 rejuv
keypress up = druid2 (and/or other druids incase stuns ect) Swiftmend

This should give a near instant swiftmend in theory.
