Exactly, as it stands at the moment, anything other than Skill Focus: MS/Hide is useless on a rogue. Unless you got for dual-wield domination, or ranged domination with a good party, there's nothing the rogue can do. It's also the fact Legion that 6/10 people, skill-dump and get access to things. If their character -could- do it, why are they cheesing the system and only putting in one rank of it? One -rank- is a god damn amateur, which is where it comes down to the fact that for a low magic world, there is way too many high bonus magical items that help boost things up to unlikely proportions. Think of it this way, in PnP, or any other sort of D&D, can you just 'quick-change' things on/off? Do the misc bonuses stack? No, that's why its balanced and unless someone powerbuilds a certain skill, you can be sure most of their bonuses are relatively low. The thing is, these guys have reasonable DCs, but the magic/consumables available makes it little more than a walk in the park.
Also, Legion, that's what the initial thread was about, people taking one level of rogue, just to dump stats in to all the rogue skills. If someone is learning, and it's not something they typically do, why not cross-class it? It's because it's easier to power-build in to rogue/bard multiclass, and have most of the benefits with little to no real trade-offs.
