Hrm...
Medios -I can't argue against you if we're talking about realism. You're right that I shouldn't be able to sneak up on someone wearing a complete set of heavy armor. But then I couldn't shadowwalk, sneak, tail, steal, purloin, etc... either.
Sloth is a four class mud, which is inherently unrealistic. It'd be hard to imagine an armored knight laying haying hands on the wounded, or raising the dead, or casting complicated magic spells.
The only way to really fix that issue would be to go to a single class system. But then this wouldn't really be sloth anymore.
Avatar - How do you know that the gargoyles are a taste of things to come? Are thieves really about to get nerfed that hard? If you know something, please elaborate.
