Vindictus takes a very different approach to combat that makes it extremely fast paced and unique. It's combat is not about using skills as much as it is about having skill. A "party" in Vindictus was (as you said) there to kill something faster and help overcome mechanics that required teamwork. That doesn't make it a bad thing. In doing this they showed that a game doesn't have to have a static, role dependent, limiting factor but instead be designed in such a way that allowed many different styles of play to come together and kick butt. No, it's not perfect, but I've never played a game where what or how I chose to play meant nothing more than how much fun I had. That's how it should be. It still has several elements of support/teamwork built into the fights/environments themselves rather than into the specific character designs. That's why Vindictus is a great team game. Not for it's static, pre-designated class teamwork, but for it's freedom and enjoyment.
