I totally agree with you on this one. Perfectly fine for resto not to find Primal Elementalist interresting (and I'm sure there will be PVP situation where this could change). Anyway, by the look at it, I don't find the two others being "solid". I would love to see another or a longer effect on Unleash Earthliving so that when you read the tooltip you tell yourself "ok this one looks really usefull / I can see in which situations I need it / it really can change my gameplay a bit". This may only be me (and again I don't know nothing about the stats) but when I red it none of this came to my mind about Unleashed Earthliving in oppositions of the other effects.
As for the blast talent I felt the same. I'm ok with launching a dps spell to gain a benefit for my heal, but a short casting one if not instant.
To me this is the kind of things we need to discuss, because if there is something needed a change, it's during beta, not after release.
PS: btw thank you Endus for the great job you did on this post.
