I chose the priest class at character creation and do was automatically given proficiency with light armour and weapons. The thing is, it seems there's no advantage to light armour and weapons other than being a bit lighter - I mean, it's not like you get more attacks a round, critical bonuses or an easier time casting spells. I feel like I've wasted all those points I put into light armour, light weapons and dexterity now.
Is there any way to reset the point distribution, either in-game or editor-based?
