Another thing to note about Aldo is that I use it as a tool to buy myself time to do other things. A great example of this is Wave 6 of turn 4, Our strategy involves burning the dread of phase 5, having the MT pick up the dread from phase 6, and the OT tanking all the knights, rooks, and other stuff from waves 5 and 6. Now in this situation I typically start out with eye for an eye on the MT or OT, depending on who my WHM buddy already used it on. My job during that phase is to split focus on the MT tanking one dread (2 Stacks usually), and the OT, while my WHM buddy heals the OT almost exclusively.

Now in this situation, Aldo is great at buying myself time. I cast it after a single auto attack from the dread on the MT, and it will prevent the subsequent attack from doing anything significant. The time this buy's me is time to spent using aldo / lustrate on the OT, who is taking much heavier damage. In essence, It allows me at least one free global cooldown to focus my attetion elsewhere, and if it's a crit that hits, then I have a lot more free time. I find that similar situations arise in turns 1 and 5, where aldo can buy me enough time to heal elsewhere.

Also your comment about using Eye for An Eye preemptively is a good concept. One prime example of using it would be on garuda extreme, right as the twister sisters (Funny name my friends came up with) spawn, E4E on the MT, and hopefully by the time she does double wicked wheel, at least one of them will be affected. Follow this up with a sacred soil + Virus on garuda right after she teleports and you are looking at significantly reduced damage from double wicked wheel, to the point where tanks typically take around 3000 damage as opposed to nearly getting one shot.

Another thing to note is that you should learn when and how you can throw in dps. What makes a SCH such a strong healer is that they can do dps at the same time they are healing. Your Fairy combined with lustrate can buy you a little bit of time to switch to cleric stance and throw up some dots, all dependent on the fight of course. Garuda Extreme is once again another great example, outside of double wicked wheel, the healing necessary for garuda extreme is laughable at best. Even while solo healing, I find plenty of time to throw up dot's very consistently during certain phases. Your dps is nothing to joke at, sure WHM's have holy, but we have much better sustained dps, and we can heal at the same time.

Another thing to note about doing DPS, an Aldo crit will buy you time, a significant amount of time in some cases, you should throw out some dot's if nothing else pressing is at hand, why waste a few global cool down doing nothing when you could help out doing damage. Another example of this is waves 1 and 2 of turn 4, I do more damage than healing during those phases, because I have learned to use lustrate / rouse effectively, and my WHM buddy knows what I am doing. Guess what, the long term effects of me doing damage in these phases show. We haven't ever hit the enrage timer, which can get nasty quickly if the last dread isn't finished off promptly.

It's these little tricks which separates the bad Scholars from the amazing ones.
