So I've played ele and enh on beta and despite what I've/you've seen they're not as bad. First of all blizzard hasn't done any number tuning yet so no point about talking about that, but the mechanics so far look great first of all lightning bolt/chainlight/lvb have a 100% chance to grant an ls charge (3 hits by chainlight cause 3 charges) as well as multistrikes have a 100% chance to generate an ls charge, its going to be easy to stack it up to 20. Fulmination can multistrike with all its 20 charges, and the multistrike of it has no travel time, thats really great for oneshots. Mana reg is also i a good spot, going oom will most likely not happen as long as you don't spam hs nonstop. The new mastery keeps attacking while you're cc'd. Unleash flame has 20 seconds uptime (up for 8 sec) which is good for preparing oneshots with instant eb, so after all that stuff looks good but we need a slight damage buff, yet fulmination hits for 27k with bloodfury/on use trinket, earthshock ~4k and unleashed instant eb ~13k, so close to 45k per toon makes up 180k total damage on pvp targets so we rely on crit/multistrike to land a oneshot with that combo, however with support of the level 100 talents it is possible though.

Enhancement dps is ok, pvp setbonus are very good but ascendance sucks hard so I hope that one gets a huge buff, though their utility and healing is still strong
