I read that and how they are kinda underwhelmed with the cascading problems in getting new gear and needing to get to a hit cap and it made me wonder why they even have that artificial cap anyway? Why not just have all things hit by default and hit rating and expertise just increase the potency some way of that hit. Like perhaps expertise makes critical strikes stronger or hit rating gives you chance at double strikes. It would make getting new pieces of gear be wearable right away and even give more depth to the gearing system by adding in more ways to customize your character and how they do damage.
I could see in PvP that it would not always be a clearcut thing on which rating is the best to stack and it would open up some different playstyles and builds within the same spec. Like a warlock that stacks mastery versus one that stacks hit chance (double strikes) or a warrior that stacks crit versus one that stacks expertise (crit damage) and relies on 3 minute cds.
