I don't necessarily agree on the specifics, but indeed the new attribute system is basically a non-choice. You decide on a primary attribute and plainly level this up, with a sprinkle of memory added to taste.

The first game had a balancing act between attributes to reach maximum efficiency. For most practical purpose the game would not lose anything with the removal of attributes and instead level based scaling. Actually, the game would gain something, because hybrid classes would work better, especially those which mix physical and magical damage.
Though a similar thing can be said about combat skills, because warfare is so overwhelming strong. I really don't know what went wrong with his game, maybe the guy who did the math for them quit his job or the game became to big to properly allow for character customization on attribute and skill level. I really don't know, but it is a glaring weakness of the system. Level ups are an pure annoyance within the current system.
