I agree, I would definitely prefer it if the player characters weren't the ONLY ones who could get anything done. Every time you get to a planet, you solve a few issues and then leave with your faction's victory practically guaranteed. It would be nice if the PCs played smaller roles, especially in an MMO, where it's harder to ignore the fact that you aren't the one and only true savior of the galaxy that seems to be such a popular trope in Bioware games.
But I guess more people just want to feel special and important.
