I just wanted to get this idea out there since there are so few of us.
In a party or raid setting, there is currently no raid debuff for nature damage, such as curse of the elements, shadow, etc...
I think it would be a good idea to make Faerie Fire apply lower nature resistance, and increase nature damage taken. As of now, it feels pretty bad to be singled out as the only caster without these buffs to our damage in a raid setting, and it fits the theme of druid to be increasing that damage.
Compounded with the fact that we are currently barred from any legendary items that benefit us (scythe of elune, atiesh are unusable by shaman). I really think that adding at least the debuff effect would encourage people to play this spec.
Currently I'm the only Ele shaman who plays exclusively elemental in raids according to the logs available. So I wanted to get my opinion out in the open.
