Every T10 build is forcing us to put exact items to every spot. Diablo 3 was not about choices , but more and more we are having more than 1 efficent enough build for every aspect of the game.
Sure, it can do T10 now, but being forced to sacrifice a ring slot just to be able to farm T10 somewhat efficiently is just bad design. It should be a option not a requirement. Most other builds/classes do T10 reasonably fast with whatever rings, faster with good rings, not like WW where you are forced down to T7-8 to not spend over a minute killing the RG without that one item.
I'm really happy that I will be able to bounty farm while WWing so I welcome this ring change
