Add Idol of the stars for moonkin druid

[Alrighty2]

The elemental shaman got totem to increase their lightning spells 's damage, ret paladin got the extra new spell to increase their damage. Balance druid only has an Idol of the moon(moonfire usually is not allowed in raid), I strongly suggest adding a new Item in the game for "Starfire" damage. even with a 20-30% increase in damage Idol of the stars, Moonkin will still underperform compared to other casters, but at least make them more acceptable in raid/PvE
