From Dark and Darker Wiki
What other class has perks to make one skill not worthless? Imagine if Fighter had 3 perks that make Sprint or Second Wind worth using. If a Rogue wants to use Hide, you are nearly forced to take Stealth, with the other 2 being optional. Rogue suffers from severe perk tax.
I wish Ironmace could decide on what they want Rogue to be, because it doesn't have much of an identity. They do damage over time with Poisoned Weapon and Rupture and have Double Jump, but Double Jump is nerfed into oblivion. Hide is one of the most controversial skills in the game but has become central to the current Rogue's identity.
