Well, this does seem like a really cool idea and it would definitely save a lot of time grinding for new armors and this would also be great for those weapons. But, let's say I already have the 55 PVP set. So, if this system existed and I would like to get the 65 set, all I need to do is trade my 55 set in right? This would save me lots of time and if everyone were to do this, PVP would be ridiculously inactive. So, even thought this seems like a good idea, this would, put shortly, ruin the game.
