I have really mixed feelings on this overall. Our damage seemed to be relevant after 6.0 when doing SoO in full BiS gear, but we are very quickly outclassed in 630-640 ilvl gear currently in Heroics, unless you pick up EM, PE and SE for enough sustained dps. Even then, if the fights were to go on for the full 5 minute duration you would find that we quickly fall behind warriors and mages just to name two classes at random.
They pruned some of our abilities, but they left others that needed to be removed. We still have a LOT of sources of damage, and we are effectively 'haste capped' with enough gear once we get to around 45-50% haste (YMMV). If I were emperor for the day, I would take all damage off of Frost Shock, increase SS and LL damage by a further 50%, remove baseline Unleash Elements (merged entirely with UF) and Magma Totem, and swap Primal Elementalist with Liquid Magma.
Doing these things removes one ability from our rotation entirely, and gives us a choice of what kind of DPS talent we want at level 90, puts more emphasis on our primary damage source abilities and keeps haste relevant no matter how much of it we stack. You need more movement? Chose UF. Like to PvP or need single target damage? Use EB. Time for some AoE? Chose LM.
