The problem with current stats-system remains: Getting closer to level 10 pretty all stats lose they worthyness. Sure, wits will still help with finding traps and hidden objects and battle stats will still increase hit chance I guess, but otherwise they totally lose they worth in combat. Because all benefits per level are getting closer and closer to + 0.1% per point. Only Wits starts earlier with it.
They also need to do something about buffs that increase stats. Even putting points into wit for traps and hidden object becomes useless when you can just pop burn my eyes and gain a whopping +10 wit at lvl 7~. More than enough to find anything hidden. These buffs only scale harder as you level. Encourage, for example, gives so many free stats.
