I disagree with you, I don't feel any of this solo content makes me a better or worse player. I get better with multiplayer content by doing it with multiple players....all most of the solo instances do at normal levels is serve to frustrate me and honestly I don't think I'm the only one on that. I want to do the solo instance stuff and be done with it then move on, not practice it(I find the idea of practicing a solo instance you will never do again once you clear it silly). I play this game for multi player interactions not for the solo stuff.
