Could someone please tell me what the point of the rogue is? I'm playing one while a friend is playing mage, and it seems to me after playing a fair amount of the game that the rogue is just a severely ineffective Ranger. Since charm and silence upgrades are all tied to the Ranger tree, which is all range combat based, there is no point to choosing the rogue preset except to gimp yourself at the outset of the game. It seems that picking the Ranger(survivor) is an infinitely better choice. Am I wrong?
