I think you answered your own question. Rogues can\'t dish out the damage a tank can, nor can they take the same amount of damage. They also won\'t have any real spell capability(unless they train that up on the side.) The balance comes from rogues and rangers speed, and skills. Rogues can hide in shadows and strike back stabs to people(hopefully waylay as well.) Rangers will be able to hit things from a distance, probably as well as tracking. The main point to PS, is that there aren\'t really any \"classes.\" Everyone customizes their own for all intensive purposes. Each possible configuration has different tactics to it. Each combination should balance in the end, it just comes down to who knows the better tactics.
