Hey guys, is Enchanter worth leveling when Velious comes out?

[Wonka11]

With the immunities on monsters (dragons, giantkind) how useful are Enchanters, both solo and grouped in this expansion?

I realize the expansion is far out, but humor me on the subject.

Group wise, they have their haste and a decent slow, but with groups having to take another off tank to compensate for monsters that are unmezzable, what are we really looking at here?

Solo wise I understand this hurts too, but we still have solo charming which can help.
