What is the enhancement in mind? How should it look and feel?
It should allow Fury warriors to equip things like lances or fishing poles from titan's grip.

Please provide any additional information below.
The titan's grip fury warrior talent allows equipping a 2 handed axe, sword, or mace in each hand, as you know.  However, when swapping to a (not axe, sword, mace), such as a lance or a fishing pole, by default, the blizzard UI attempts to swap the mainhand weapon with the new item, rather than un-equipping the the offhand 2 hander first.  This results in a "I can't put that there" error.  The same can be seen by being fury spec, then swapping to tank spec before attempting to equip your sword/board setup.   Rather than unequipping the offhand 2 hander first, it just fails.

Making the offhand 2 hander un-equip prior to swapping the main hand weapon would fix this annoying issue.

I just noted they "sorta" fixed this with 3.2. It now allows swapping in, specifically, fishing rods. However, lances still error out.
