Just wanted to drop in and say, as a balance druid, it would be better to do nothing than to spam moonfire/sunfire or starfall (which is still just a death wish in a lot of cases till they fix it, as always lol) at non-optimal eclipse times.
We do have Starsurge (in wod) that can be instant, if it's up and your charges aren't tied up in upcoming rotation.
That is our plethora of instants. Can't even toss down shrooms anymore on the move. If we were to use our "spammable instant with no cooldown", more often than not, we would do less damage overall than standing still. How's that for "Fun gameplay"
