If you can't get past the lower level content that is intended to be beaten solo, what will you do once you hit 50? You won't be able to "go level some more" if things get tough. The level cap is intended to make it challenging, and help you learn to strategize. If you can't or simply don't want to put in the effort to learn, perhaps this isn't the game for you. As stated above, no one doing any end game content is going to want someone in their party who hasn't learned their job and going "easy mode" though all of the lower content is a sure fire way to accomplish just that. Do yourself a favor and try the content as it is now, even if it takes a few tries to get past that tough battle.. You'll be a better player and have a better sense of accomplishment when you've beaten it.
