Well, here is my little opinion :
Rogues are great BUT you can't play
them like a figther.
Dual weapons is a waste of feats, because
you don't have much of them and at best
you will have a -2 to hit penalty with
each attacks. If your second weapon isn't
small, you will have a -4 penalty
Rogues are powerfull in combat when they
could use their sneak attack. So it's very
important to get the initiative to caught
your oponent flat foot or to strike from
behind, ...
But you can't use a sneak attack on : undeads,
constructs, Ooze, Dragons, Elementals (any
creature witch is not subject to critical hits).
If you fight thess type of creature : you're
history.
It's very important to have very good reflex
saves : avoid traps, and fireball like spells
(evasion).
The best race : the hobbit.
And take feats like : improve initiative, dodge,
mobility, Iron will, Lighting reflex, ...
