For example: Patch 1.05 Known Issues (ths is LAST SEPTEMBER)
The worry is the new gems will bring this issue MUCH more visibility because the gems will affect different weapons at much different levels, and may end up getting "fixed" eventually.
Personally, I expect nothing to happen, go live and Blue/Blizzard wait to see how the min-maxers react to the new gems and then nerf/buff accordingly. Would you expect anything else? ( http://i.imgur.com/Cn4sKCel.png - makes me believe they don't care or even know what is wrong with the affix )
