I've read the protection thread here, the protection thread at Elitist Jerks, the guide at Icy Veins, and used Ask Mr. Robot and all the sites seem to have conflicting information regarding what gemming strategy to use and when to look at which strategy. For example, AMR suggests I use the following with the default "Control/Haste" build:
Yellow: Haste/Stamina
Blue: Stamina
Red: Expertise/Stamina
I've had several people say this is incorrect for the most part (outside of raiding heroic content where you need more stamina to survive) and that I should gem like this, which I recently regemmed to:
Yellow: Haste
Blue: Haste/Stamina
Red: Expertise/Stamina
Now, I am a 10-man raider and unlikely to see heroic modes any time soon; my guild just downed Tortos on normal this week and will be starting progression on Megaera tomorrow. At the moment I'm exactly at the hit cap without excessive reforging (being a Draenei helps) and very close to hard capping Expertise, so it seems like I'm at that point where I should throw everything else into Haste, but having recently returned to Paladin tanking I still get confused regarding the notion of actually wanting DPS stats instead of tank stats in most cases, and the gemming strategies seem to be entirely reliant on what content you're doing, how comfortable you are with the class, and various other things, so I'm more than a little confused still about which way I should be gemming. To make matters worse it seems I could also go for for heavy Mastery as a viable (and possibly better overall, according to the EJ thread) alternative to going Haste-heavy, wherein your SotR is less predictable but your overall damage intake is smoother and less prone to spikes due to an imperfect rotation.
