IMO just keep this thread stickied or something with constant updates to the stat priorities.
Druid (Restoration) : Spirit > Mastery > Haste > Multistrike > Crit > Versatility
Dependant on druid's playstyle could also be: spirit > haste > mastery > multistrike > crit > versatility
Stat priorities are way too dynamic, sure your main stat (eg frost mage, multistrike) won't change but your second will.
