***Note: this article is geared towards paladin tanking, but may be applicable for other tanking classes as well***
One of the main tanking topics that’s still up in the air is how tanks should gem/enchant/reforge. While I’m newer to the tanking field than some of the tank bloggers and numbercrunchers out there, I think this is a prime opportunity for an experiment. The idea is that since the tanking mastery Divine Bulwark provide strong mitigation, it may be wiser to push our gear towards stats like mastery. Unlike dodge and parry, blocks don’t suffer from diminishing returns. Because of this, reforging dodge and parry on your gear into mastery results in more overall mitigation. As a bonus, I’ve noticed that mastery rating tends to result in more overall points than dodge/parry rating does, so this also contributes to greater mitigation.
Currently, I’m using gear that utilizes the following gems: Puissant Dream Emerald in green slots, Defender’s Demonseye in red slots, and Solid Chimera’s Eye (I’m a JC) in blue slots. Prismatic I fill up with what I can, leaning towards the emerald if I’ve already got all three JC gems in my gear. Now! As a quick, brief test, I purchased the recipe for Fractured Chimera’s Eye. As a JC, I found it frustrating that there was little to no information in regards to whether or not it was better to use stam or mastery JC gems, so this is my first test on the matter: I swapped an Emerald for one of my Solid JC gems, then replaced an Emerald that was in a yellow slot (+10 parry rating bonus from Gryphon Rider’s Boots) with one a brand spanking new Mastery JC gem. Here were the results, without Blessing of Kings or any other buff active – just wearing my gear:
Before: 144,217 HP / 10.27% parry / 12.16% dodge / 54.56% block / 81.99% total mitigation
After: 142,509 HP / 10.27% parry / 12.16% dodge / 55.41 % block / 82.84% total mitigation
Conclusion: Trading a Stam JC gem for a Mastery JC gem (aiming for socket bonuses) essentially trades 1,708 HP for a 0.85% mitigation increase.
Now, my blocks stop 31% of damage due to block enchants, so keep that in mind, but what this test ultimately means – in my opinion – is that JC paladin tanks should definitely use Stam JC gems over any Mastery equivalent (nor parry/dodge, since they provide less mitigation than mastery does). Does this mean we should not gem for mastery at all? I doubt this is the case, but whenever I can arranged for the funds to test this theory, I will. Until then, I hope this brief experiment will help you choose how to spend those hard earned Illustrious Jewelcrafter’s Tokens!
