I read skills and feats would not be mandatory in DNDN which was fine because we play AD&D as rules-light system without skills. However, when I look at rogue in the Playtest, I see the skills are probably mandatory. My question is: Is skill system mandatory when a player in group wants to play a rogue? Is rogue valid even without playing with skill system? Becuase as I see it now, it would require too much house rules for rogue to play without skills.
