It does not proc or is a passive buff like shaman, pally or priest mastery, and is only a short duration buff. Monks will also be a proc type mastery if it is kept in current form from the beta to live. In PvE it is not as much of an issue, however, in PvP sometimes to hard cast would mean to be interrupted. Not to mention times where you may not be hard casting but rather placed some hots they are not buffed because it is required to hard cast to get the buff. In order to keep it up the druid needs to cast a hard cast spell roughly every 8 seconds.
