note: the chance to trigger effect 1 is 7% in Legion instead of 5% displayed in 1st wowhead link - this is confirmed by changelog on wowhead and attached screenshot from Wowaddicts Legion server and client

I've only tested effects 1 and 2, which apply to Guardian spec druid that I play. Effect 1 wrongly consumes buff granted by effect 2 (2nd link) in the same talent activation instance, so whenever the talent is triggered, it automatically casts the "improved" Moonfire and grants 8 rage instead of casting basic Moonfire and granting a buff that would apply to the next Moonfire the player casts. I'm not sure what should happen if the talent triggers again before the buff from previous activation is consumed by the player, but 1 comment in 1st link suggests it should consume the old instance of the buff (the automatic Moonfire would be improved in this case) and apply a new instance of the buff which would be again available for the player to use as they see fit. This would make sense, but I couldn't confirm if this is how it was actually implemented on retail.
