Paying attention to your average skilled, keyboard turning, button clicking, backpedaling player, the strategy and thought that goes into killing an operative and understanding the player's role was deemed too difficult by the average $15 dollar/month player. It wasn't the class that was balanced, it was BW's checkbook.
Before you post, ask yourself this:
How does your gear look compared to the TOP players on your server? Is it close?
Do you find that you always have 3-7k less HP than the people you are playing against?
Do you do the things I listed earlier? This includes but is not limited to keyboard turning, button clicking, and backpedaling.
Are you even level 50?
If you can answer "Yes!" to these questions I will greatly appreciate your input
edit: adding more things
are you playing a spec that is a PvP build? ex. if you are a sorc/sage that doesn't have the stun on shield break, don't post
Does your computer run the game well? This means 30+ fps
Do you play your class to its full or almost full potential? (if you have to ask it's a no)
