Both of those two skills got a higher DPET then Elemental blast, which is what you count when you rank the spells. The buff you isn't worth casting it over the other two spells named above. You can test this yourself by changing the rotation order in simcraft.
Offtopic: I think Elemental blast makes the rotation alot more fun, even though it's a 12 second cd it's still an extra thing that you have to look for /do. Feels that we have so few spells not counting that. I like that it's around a ~3% damage increase to use it, and hope they keep that number.
