What drives a poor reputation for the Rogue class?

[Skrum]

Note: The SA Dice and Stat Bonuses might look off in the Spreadsheet.

That's because the Rogue does +2d6 on a hit (from magic item) and has +1 hit and damage (same).
The Barbarian has an extra 1d6 damage built into every attack, and the Strength boost reflects the +1 to-hit and -damage.

Against AC 19 rogue is slightly ahead! That's a feather in their cap at least. Pretty cool chart.
