So far I'm seeing no changes to Ele shamans on 5.4 ptr so I'm interested into your opinions on the current (and come 5.4) state of Ele. I'm a low ranked player (1700 2s, 1600 3s) so I'll not pretend I pvp well.
In my opinion Ele is fine at the moment. I struggle a lot against any (mostly melee) spec that can tunnel/shut me down effectively. Namely, rogues (cc, cloak) and ferals (immunity to hex and roots if played decently) are the biggest pain in the ass to deal with. Also healers that purge flame shocks will gib my damage by at least 50%.
That said, under CD's I'm blatantly OP. When I ascend you really wanna chain cc me until it's off. Also, never ever let me free cast cause 2 lucky procs will probably get you killed.
To counter me, the best thing to do is cc my team mate(s) and tunnel me to death. I lack immunity cooldowns (bubble, deterr, block etc.) and my defensives aren't that great (30% damage reduction on a 1min CD, heals). Make sure you don't get rooted -> capacitor and most likely you'll kill me.
I'm very interested in hearing what you fellow pvpers think on this topic!
