Quote from RuppguRemoving stats from gear is always something I will be VERY against in this game.
The current itemization is already VERY limited. Everyone is after the same stats. Removing the usefulness of Pickup Radius would only make items even more stale. If you don't like how things are with your current pickup radius, then swap out a stat for some more. It's called a tradeoff.... and it's a good thing.
Can't have your cake and eat it too. It should stay the same. My main is my monk and he has zero pickup radius. It is annoying, I agree, but you can't have everything. I saw the benefit of this even more when I started playing my barbarian as a whirlwind spec. I saw the benefits of having it on his gear even more that I made it a point to grab at least a piece with +5 pickup radius. Which made all the difference in snagging most of the gold as I plow through and grabbing health globes with elites.
