My personal view is that the intelligence-based xp boost in the end allows a player to enjoy a higher level character longer and therefore not a problem. What I DO see as an issue, however, is the number of weapon points I am ending up with lately: nearly 900 accrued between my last level and current. I don't have the agility to have the weapon mastery to assign them where I would prefer them so they kinda get stuck wherever, making me all but unstoppable in tournaments. That is a bit much I think. Even at
level 39 on day 397 (I advanced to that about a week ago in-game) I still have to choose between the base attributes in order to get things the way I want but have no such problem any more with proficiencies where I am, unfortunately I believe, a jack of all trades. Below are my stats:
Edit: the first thing I did was push my INT to 15 where it has served me quite well since.
