It is sign of a poor RPG, if attributes only affect combat.
Honestly, they probably just could remove attributes at all, it probably would support the classless system much better than the current system does. Current attributes do not offer any kind of real choices, making leveling up attributes pretty unchallenging and boring. Such a attribute system is expectable for low budget cheap indie game, but should not be in a game like D:OS, even more because the system in the first game was much better.
