No offense, but here's why I hate AMR:

I don't care how much you rationalize it. If I miss a Chaos Bolt that's powered up by 30k+ worth of intellect procs and dark soul, because my hit was at 14.99% from AMR's recommendations, and my raid subsequently wipes over it, that's still my fault. It's my fault, because I put my own e-peen and recount obsession over actually killing the boss. No two ways about it.
Following their logic, no one should actually go for the hit cap of 15% and are probably better off staying at 0% hit. I mean, it's only a 15% chance right? which means you'll hit your attacks 85% of the time. And better yet, you'll hit harder and faster since all those wasted points in hit now go to crit, or haste! Amazing, right?
Btw I love this bit:
That post is almost a full year old. We're still waiting on the "mathy description" of why is it a good idea to be below the hit cap. My gut tells me there is no mathy explanation. Not capping hit is a bad idea, period.
Don't get me wrong, I think AMR is a great tool, and you're right that anyone that can use it to its fullest will benefit the most from it. But that's true of any such optimization tool. What I hate about it is this misinformation about hit, which causes players to argue with me when my hit is at 15.02% instead of 14.75% so I can have a bit more mastery rating.
