When you have a 1H weapon and something in your offhand, you cannot right click on a 2H weapon and swap out the 1H and off-hand for the 2H. In order to remove the gear you have to drag the offhand out of the slot and then you can right-click on the 2H. This makes it very difficult to compare stats between these types of gear sets. It would also be appreciated if you can look into a second layout screen where you can have say a 2H bow in one and a weapon+shield in another for classes where builds are focused around both item types.
Thank you for your time and consideration!
