Well, the lack of choices at level up is alleviated by additional skills, more levels to gain (or should I say shorter level ups) and better rune giveaways than KBTL.
Actually, in KBAP you can reach much higher attribute values than you did in KBTL because of those skills. Warrior with 40+ Attack? No problem. Paladin with 60+ defense? No worries. Mage with 65+ intellect? Bring it on
EDIT: To correct myself - the max intellect value before shrines and other bonuses is 70, which transforms to +500% spell damage. NOW - BRING IT ON
EDIT 2: Max values for now seem to be around 48 attack (before bonuses), 61 defense (before bonuses) and 70 intellect (once again, before bonuses from shrines and game objects). These values were unthinkable in KBTL
Well, I may have exaggerated a bit, because it's also a matter of luck - you should be downright lucky to get all the items you need to get such a high attribute value to spawn in one game, but... You can still reach some new heights you were unaware of - and in much less time that in took in KBTL.
