I was playing Ele Shaman all through Cata, some of the worst gaming experiences in my entire life were in 4.1 because of how terrible it was. They buffed but they didn't even fix the major problems ele had, I had to quit in 4.3 because of how dominant rogues are over ele and how common, FOTM they are now.
A lot of classes are being made redundant because of how stupidly op rogues are, they dominate everything...even without PvE gear. I now play Hpala to avoid the grief they bring but as of late, more and more rogues are being boosted to legendary daggers.
I got bursted down from 100% - dead (166k hp) in less than 8 seconds from the legendary dagger buff as a hpala with 4.5k resilience while popping some instant heals as I trinketed the quick kidney after cheap. Most classes solo can't even get me below 75%.
Completely broken class, even fire mages and feral druids looks super-weak compared to this. It blows my mind that even though the expansion is coming, no patch or hotfix is coming to alleviate the issues. It's like leaving a broken tap on for months.
