Brain Dead Builds
In non-tournament modes, yeah, it’s pretty much it, although it always depends on your skill. In organized teams, different builds have a lot to offer, and in fact hurr durr builds suck tons.
In gw1 creativity was well prized in pretty much all modes
Wrong direction of causality.
Braindead players can achieve acceptable results with strong builds because the builds are strong, not because the players are braindead.
