That's the only way when I did the character creation. But I am glad that we don't have to do the dice roll one(which is a cheat engine magnet), so I guess it means in order to gain from 16->17 I would need to subtract more points from other stats just to level up 1 point.(cause that + button didn't light up when I reduced 2 or 3 points from Wisdom) but it seems that's very costly trade. A point to point seems more fair and let you create some crazy biased char out of gate.
