I just deconstructed a maxed out level 60 bow on my hunter with over 1,000,000 points of xp and got back only a 300k xp rune plus some relics and then I decontructed a maxed out level 40 second hand weapon with over 600k xp and got back a 87k xp rune and relics.

Is getting this little of my original LI xp back after decon typical?

I spent months grinding xp to get these weapons to max level only to be sorely disappointed in the amount of xp returned!

Is there an optimum time to decon to get the most xp back or is it totally random and I just got ripped on these (my first two decons)?
