If a game relies on detective work and perseverance to uncover pretty basic build planning, then it's doing it wrong. Beyond that, it is the case of too basic info given. The hero planners (Mid's previously and Pine's now), got most of the details down, but still too lacking. Guess I'm a little surprised a game who seem to have a surprisingly decent playerbase, doesn't have a wiki that matches it.
The Wiki's pretty thorough though, it explained exactly when the blasters lost the endurance crash.
