I think any conclusions on the rogue design is a bit of a over reliance on a single set of data. This actually shows that our rogue is the only one in the group that is much of a marital (so yes, for us he's dressed up like a fighter), and only non-caster, in the group. There are also some house rulings around crits and poison that allow him to do insane single hit damage at times. As well, he's always the one doing damage (it's his one stick). The other characters are often busy solving other problems or solving them in other ways.Those rogue stats are a pretty strong condemnation of the design as anything other than a front line fighter dressed up in stealth cosplay.
But, it does show that at least in our group, martials hit more than caster's spells do. But again, those numbers ignore that many spells still have an effect on a save and that casters are not just doing damage.
