What drives a poor reputation for the Rogue class?

[Skrum]

Last game, rogue drank potion of haste. He could drop a healing potion on a downed party member AND sneak attack on the same turn. Also, while hasted: Hasted action attack once. Regular action ready an attack to attack the enemy when the enemy does anything. Result: Off-turn sneak attack.

Clever! I stand corrected
