an intruder would be the rogue/assassin of Guild wars.
class unique tech would be something like "Turncoat" % chance to send character into a # attack speed increase(slight)+ the % chance to Increse the chance to crit..only when using a Intruder skill.
New weapons such as daggers would follow this class
other techs would be
Camoflague or stealth..stealt buffs/moves
Ruthlessness ...fast Hit crit moves, cause exausion
Dagger mastery...%to crit+ more damage Etc while using daggers..
id like for there to be another melee class besides a warrior.
NEW CLASS IDEA: Intruder
Traps
