I skipped most of those pages, but I kind of get what C&E is saying. The two most over rated parts of this game are group composition and builds.
Not saying that a poor build (or an unbalanced group) isn't possible, but the extremes that it gets taken to is ridiculous. It really doesn't take much to make an adequate build, and after that, figuring out the optimum numbers might be a neat intellectual exercise, but it's unnecessary. Put it another way, I would much rather team with someone with a sub-optimum build who pays attention than a clueless guy with a tricked out toon.
BTW, I love everything about playing blasters. I like the piles of defeated foes when it is easy, I love the challenge of staying alive when its hard, I love the one-shot snipes, I love figuring out how to keep shooting immediately after you nuke, I love....you get the idea
