I like using a variety of weapons and armor while leveling, usually based on the level of the item. But now I'm starting to get blues and purples and I have no idea when a blue becomes better than a purple, a green over a blue, or a green over a purple while leveling. It's easy enough to compare when it's a 2 hander vs a 2 hander, but the lines are very blurry when comparing a light vs heavy armor piece, or 1h vs a 2h. I know in other MMO's, a purple may be better than any green you get for 9 levels or more, whereas a blue maybe only about 5 levels. The way gear is weighted in this game is unknown to me, so it's hard to figure if the item that drops is actually an upgrade or not to what I'm using, unless of course, it's the same item as I mentioned earlier.
