[*]There are bugs (like sneak attack damage for Rogue is suppose to increase over time, and currently doesn't in EA)
What do you mean ? They actually increase with your character's level (at least if Larian's formula in the log is implemented)
Sneak attack damage is suppose to add an extra 1d6 every other level. So 2d6 at level 3, 3d6 at level 5, etc. At least when I played EA it wasn't increasing at level 3. This is a rogue's way of staying roughly on par with other melee classes who get extra attacks at 5th level (and sometimes beyond) where the rogue does not get extra attacks.
