My tips (and several of these have been mentioned before):
- Ret aura, not Devo
- Sanctuary, not Kings
- Divine Plea early, as others mentioned.
- Drink any time you see your healer drinking. If they're not drinking, you can likely stress them more by taking more damage (relax Holy Shield priority, for example).
- You seriously can't drink for 4-5 seconds before the next pull? I will do that while I am marking a skull.
- Are there timer based achievements that require you to chain-pull, aside from Stratholme and Pinnacle? (Old Kingdom can skip 2 bosses and give you 20+ spare minutes for its daily.)
- I have a stack of potion injectors and super mana pots ... and use them rarely. When Plea is on cooldown I'll consider using one -- 3200 mana is almost 3/4 of my mana pool. They're probably quite cheap, now.
Conservation tips:
- Consecrate once, if ever, and only if there are more than 3.
- Shield toss, change targets, shield slam, change targets, judge, change targets, hammer. After that, hammer and blocks (along with JoW and such) should be enough to keep you up for the fight.
- Once you have a reasonable threat lead (say, half the mob's health?), you can swap to a different target, which lets you go into relaxation mode earlier in the fight.
I am quite inefficient, and still think little about drinking while we discuss strategy, or while marking a skull/X. If I used Plea earlier in fights (which I forget to do), I'd need to drink less. As it is, I'm more excited contributing to damage.
