My group is discussing what is going to go into 4E armor class and how it will work. Right now we are using AC against all melee attacks and Reflex vs. all ranged attacks. The problem that I have is that it makes no sense to me that their would be no benefit to having armor vs. arrows, thrown weapons, slings etc. In addition it makes no sense to me that a dragon or other such creatures thick tough armor would not also help deflect, if not outright stop arrows and the like. In addition if a character is wielding a spear in melee, but can't hit due to the opposed creatures (or character or whatevers) armor why should he suddenly have a much better chance to hit if he throws the spear? It just does not make sense. I think reflex to hits are going to apply to things like breath weapons, spells, etc. Things that armor can not protect you from logically. Does anyone have any thoughts on this or any links that you have seen regarding this topic? Thanks.
