Starfall ignores CC, your state of combat, yet it's a huge DPS contribution. Why exactly isn't starfall fixed yet?
In general, we like players to have to have to pay attention when using AEs.
Okay ever since the "fix" in WOTLK (midway through ICC) where Starfall would not hit CC'd targets, or OOC mobs it was really just oversight on the devs part. During WOTLK + Cata, they were basically shifting responsibility of players' need to be more attentive.
Now, if there's a target that cannot be DPS'd, or should not be DPS'd, basically Moonkins must simply not use one of their primary DPS abilities (Starfall is more than 15-20% of total dmg done) because they are being more attentive.
I understand you wanting to do this for hurricane or typhoon, which are *targeted* abilities. The problem with Starfall is that the user has absolutely NO control over where it will land. How do you be more attentive with it except, not use it at all?
The simple solution is a major glyph that allows starfall to hit only your current target, and reduces number of stars by X. But of course, that's been suggested only a few too many times and the lack of balance glyphs (read: ZERO) that alter/interact with our primary damage spells is an old topic to complain about.
Please Blizzard, I hope whoever reads this understands the Balance Druid tree and reads the feedback that's been delivered in a very polite and constructive way before your own devs start telling us to be "more attentive"
