Cover wouldn\'t provide damage reduction, just make it harder for both sides to hit.
After all, if you stand behind a tree, what are the chances that you can hit someone on the other side of the tree, or vice versa?
Either you\'re covered, or you\'re not.
I\'d go a bit farther than that.
Either you have partial cover, or full cover, I say.
Partial, would be peeking out from behind a tree, and so, you could hit others will a slight inconvenience (They have more room to dodge attacks,) while you have a better chance of not being hit.
Full cover, is more like where you cannot see your opponent (And therfore can\'t hit them), and they can\'t see you (And can\'t hit you).
But I don\'t think cover justifies a damage reduction.
Sure, it\'ll affect hit chances, but if I hit a player who has, say, 20% cover from a tree, it\'s not going to hurt less, as Kiva has said.
Thats why I said players have the ability to \"USE\" cover when doing so.
Ability to use cover? As in choosing? Like I choose whether to use this wall which covers me from my opponent, if not, it acts as if it doesn\'t exist?
In general, with some objects, that\'d work, like bushes.
But, for solid objects which present a physical barrier, I\'d think that, regardless of whether you choose or not, if you\'re fully covered, or even partially, you\'d get the cover if they attacked you.
Especially if it was like a surprise attack, another player cannot, or should not, be able to attack through a wall and hit a player, unless the attacker had some ability that allowed him to.
All in all, I think it\'s a good idea, but I do agree with Kiva in the fact that standing near an object shouldn\'t necessarily provide cover, or provide damage reduction.
