Mirror of Broken Images plus Divine Protection Macro would appear to be a very solid combination.

Use: Increases Arcane, Fire, Frost, Nature, and Shadow resistances by 400 for 10 sec. (1 Min Cooldown)

The use effect stacks with Mark of the Wild or Blessing of Kings.
497 resist = an average of 45.83% less damage taken.
400 resist = an average of 40.51% less damage taken.

That in combination with Divine Protection providing 20% damage reduction and being on the same schedule with a 10 second effect and 1 minute CD.

I havn't tried it yet, but putting these two on the same macro key would make sense.
Anyone doing that?

I posted about GoAK and the glyph a few pages ago. It's 30%, even if the tooltip while active says 50% - tooltip errors aren't exactly uncommon in WoW.

As far as using Glyphed DP and Mirror of Broken Images, Glyphed DP is more powerful. You already have 25% spell reduction with Aura/Totem/Shadow Prot. Using the Mirror means you take 50% dmg, using DP means you take 45%, which means its 10% more powerful. Plus if you have a 2nd on use trinket, it'll put most on a 10s CD.

Binding both together, glyphed or unglyphed, is pretty silly - it only limits your options. Using glyphed DP and mirror vs just glyphed DP is a difference of taking 45% dmg vs 30% dmg - significant, but unlikely to be necessary. If it's just the 20% DP, then it's even less worthwhile to use in conjunction, barring specific abilities, as combining the CDs just reduces their effectiveness (in terms of dmg mitigated #)

Going up a bit further, to the mitigation v threat conversation; CTC/Avoidance is never a bad thing. You ease the load of healers and are less likely to have to burn CDs. You only need enough stam to survive what's being dished out, and it's a lot easier to swap on a stam trinket than reitemize your entire gear set, especially this early in the expansion. On the other hand, threat isn't an issue until it is. Wait for it to be a problem before fixing it, because most people aren't close to having an issue. Tricks or MD are likely to cover the chance of a weak bit of agro on the pull, and you should be generating more than enough once threat is established.



For the post below this one, I'd argue it's worth glyphing on at least Twilight Ascendant Council (1/3rd of the dmg taken is magical, and it comes in predictable bursts), Nef (having a CD for every 10% dmg dealt without burning emergency timers is awesome), and H. Maloriak as well (with just Mirror + glyphed DP, you can mitigate massive portions of 4 of his breaths during black vial, plus each phase has some magic damage).

Elixir of the Guardian provides 1020 armor instead of 900 with Mixology.

Also, I believe that Caustic Slime is nature damage and can be partially resisted.

Did you talent into the more mana efficient Consecration with 2 points?
That will reduce mana cost by 80%.
If not, Consecration is likely costing you about 50% of your mana per cast.
By using the talent points, it drops to consuming only about 10% of your mana per cast.

Use Judgment more often to regain mana.

Glyphed SoT adding +10 Expertise is one of the best point gains we have available to us.
Mana should never be an issue where you feel that SoI is the solution.
If you gear, reforge, gem for avoidance and mitigation (Mastery/Parry/Dodge) that will prevent far more damage than the healing that SoI provides.
