There has been a lot of discussion lately about abilities being purged or going passive. Stealing an idea from The Queue for this week's Community Blog Topic, do we need an ability squish?
I am an altoholic, but I mostly play my monk or my druid and both of them have abilities overflowing my UI. I have some of them hotkeyed and macroed, but there's only so much my mouse and keyboard will hold. And frankly, particularly on my druid, I don't ever use some of the abilities.
Soothe is one of those abilities. When it was called Soothe Beast, it was completely useless. Now it gets rid of enrage effects, but I normally just solo on my druid and never remember it's there. Hibernate is another. Because it can only sleep beasts and dragonkin, it's not very useful and I tend to AoE instead of use crowd control in situations where it might be useful.
