Everyone can solo, as there is a lot of solo content around. Everyone can also get their **** whipped when they try to take on too much.
In the Scout class there are many types. Assassins will have the highest single melee hit with a blade. Rangers have the highest hit with a bow. Brigands and Swashbucklers get good damage plus buff/debuff. Troubadour/Dirge are more utility with tons of buffs, debuffs, and control songs.
All Scouts get Sneak, (Brigands also get a group sneak), and Escape (emergency evacuation of the party to a safe location), along with some other abilities.
Keep in mind that Scouts can't wear plate armor and can't stand toe-to-toe against a hard mob for very long. They do their best damage from behind.
