As a matter of fact u do have an addon capable of that; vuhdo. It creates a filling circle in the raid frames.

Thank for your always helpful information.

Now on using it on the field. Beside the obvious PI+AA+SS macro, it is important which groups will be targeted for each of the PoHs. Would be speaking from 25m perspective because I don’t have 10m experience with it and frankly there aren’t very many ways to use SS on two groups with two tanks. Besides fights with constant aoe dmg, I prefer to preshield limited amount of groups instead of blanketing the whole raid. The remaining group(s) can be snipe healed overally faster by the other healers with much lower overhealing, given the expected instant aoe won’t kill them of course. This means I would cover 3 groups two times and if there is a 7-th poh, I would decide on the fly where and when to apply it. If the aoe dmg comes mid cast, I might opt to use the 7th poh on 4th group before redoing first 3 so that people there don’t die before other healers react. Or if shields are fully or substantially absorbed on one of the first groups, I would consider repeating it. Normally I would use IF at the end for a regular PoH, which to cover the eminently damaged nonSS-ed group but now with SS benefiting from IF, I would rather empower my last SS poh, after having time to decide where better to land it.

If the incoming aoe is on a strict interval, you can use SS some 22s to 15s before it happens, considering you don’t forget to use it immediately after coming off cd. But if the boss ability is rather on a cd, max 15-18 would be recomended so that older shells don’t expire before boss decides he’s into doing it. Generally the (N-3)th or (N-2)th poh groups will be in danger of suffering from this so this is why I may opt to refresh that group with the (N-1)th or (N)th cast if I see that the shell on 1st or 2nd group (tanks, melees, etc) is already close to eaten up due to regular dmg. Even if a stack is lost their lowish one is better sacrificed than losing an untouched stack. Wind Lord’s Rain of Blades has an annoying cd of 50s so a SS rotation of -20s, -10s, 0s, barrier, repeat would be perfect. But more often than not I tend to have shells expire due to him forgetting to cast it “on time”. So I prefer to start at -15 or -10. Here comes the fight knowing part. And this means real field experience not just reading ability timers and calling it done.

@Adinne, I would move AA before Cascade in your spam macro/rotation. It lasts 18s and would cover your 6th(/7th with PI) PoH even with that extra GCD. PW:S could also be considered between Cascade and SS – honestly mana is not an issue for Disc and even if Rapture is on icd the extra HpS from the shield is not a waste. On most encounters there is a non-tank target that would benefit from the absorb and/or the run speed. You get Borrowed Time and even if it’s not enough to squeeze another PoH into the shell, it could buy a spare split-second slack time covering cases of lag (Elegon 25 anyone..) or accidental casting interruption happens / is required.

P.S.
SS+IF is currently bugged after 5.1: once IF is used during SS to create a shell on a target, the crit effect sticks to SS casts for the remaining of your login session. And you are free to use it on cd off-SS for regular PoHs. Hope it’s fixed very soon before it’s flooded with spoiled heroic logs.
