This is an issue that even some of our most educated and math-savy players could not make gear decisions without the help of external tools. We're much less concerned about more casual players because the specific choice of upgrade will mean less for them (skill outweighs the contribution of stats for all but the absolute best players) and they often choose pieces based on things like art over stats.
I'm talking about very hardcore raiders who no longer could eyeball a piece of gear with any degree of authority. I might believe that some very few of you are so proficient with the math as to be able to eyeball the stats, but I think you are vastly overestimating the number of players who can or do. Remember, the formula to convert armor penetration into damage was so complicated that we had to take the unusual step of actually spelling out how it was calculated.
It is absolutely dumbing down the game and removing yet another aspect of the game that gave it depth. There is only a limited number of items designed for each class/spec and you will only see a small number of those drop. If you just picked up items that are obviously designed for your class/spec with highest ilvl, your gear would be perfectly fine for the content that we have today. Those of us who want to spend more time can pull out a spreadsheet and analyze every last detail of their gear choices to squeeze out more performance. Furthermore, unless they turn the stats into a completely trivial system, a spreadsheet will still be needed for analyzing gear.
This change has likely nothing to do with improving the players' experience; It's more likely that Blizzard has realized that itemization is hard when the stat system is complex, so to save themselves some time and effort they just make it simpler.
