Here is a review of some really great tournament PvP, and the commentator goes in to good detail about how powerful the conditions are. He also shows that there are some really amazing ways to counter all of those conditions. The trick is good coordination.
Just wait for the game to be released and you will start getting use to thinking about when and how best to take care of your condition damage. It won't be as big of a deal once you're dealing with it daily.
