To answer the OP, I would say a alliance warlock will be hell because of the hundreds of ganking undead rogue and mages
That's not the hardest by far. I played human lock in vanilla, and yes it WotF was cancer, but with a little bit of gear it wasn't too much of a big deal (especially as SL, or with the use of engineering) unless you count rogues with godlike gear.
With the old old WotF that lasted 30 seconds (if I remember correctly) it was the true cancer. You couldn't do anything against rogues. I can still remember the frustation, ohh it was so bad!
