well about the XP for monsters etc
the amount of XP by killing monsters lowers every time you rank so use wisdom to get more XP from monsters doesn't pay you well in fact the reverse is true meaning that if you kill and monster and get 50 XP + 5 from wisdom means 50 -5 so you get 45 instead of 50 and because the XP lowers with every level you gain it will be even lower so. I don't know if they gonna fix that but there are some way's to counter this
1) as the game surgests exploring is GOOD so first kill all monsters.
2) when you kill the monsters you have accumalating alot of quests , now is wise to spend points in wisdom because quests XP are fixed and allways the same amount of XP add wisdom there and you can maxamize your amount of XP
