In PvE I don't see it as such a bit problem but in PvP it sucks. I don't see other classes/specs having to choose (as elemental does) between their big damage contributors (FS/ES) and slowing someone down (Frost Shock does like no damage anyway), especially now that everyone has several ways to get out of snares. The closest thing to this are paladin seals but still seal damage hardly compares to the system of flame shock, lava burst, surge procs, etc. Just another old relic of an ancient age. I truly hope shamans get a revamp in the next expansion and shocks get unhooked from the common cd.
