Daystar set and your piety.

[Menae]

I actually traded that extra 30MND for VIT... then again im a SCH so that 30MND only really gives me like 100 extra HP healed. if someones gonna die from not getting 100HP they were gonna die anyway.

I'm not a huge fan of trading Mind for Vitality except for very specific reasons.

Vitality is mostly useful for allowing you to take bigger damage spikes. It also affects how long you can wait between cures on yourself for smaller sustained damage pulses (think turn 2 damage to the raid), but in general this type of damage is very manageable without speccing into Vitality, so we'll set it aside for now (It's not that Vitality is useless for this, but it serves merely as a buffer to increase the time before you HAVE to heal). If you need more hp to survive the burst of the fight, you've no real choice - find a way to get that hp. The three ways to accomplish this are (from best to worst in terms of stat loss):

1. Increase the ilvl of your left side pieces (+shield if you use one). These all have vit on them and increasing your ilvl will naturally give you more vit. As a nice bonus, this increases your mind and relevant secondaries as well, however it may not be an option unless you terribly undergear the fight.
2. Swap out Allagan/Daystar/whatever healing accessories you use for crafted with Vit melded. This is expensive as hell in gil terms, especially if you go for the best possible melds, but is not as large a sacrifice in healing power as:
3. Swap out Mind for Vit in your stat allocation. It costs you one Mind per Vit, which is by far the worst trade insofar as healing power is concerned, but if the first two are not options, then this is really your only choice.

If you have to sacrifice Mind to live through the fight, so be it. That said, at full i90, the only thing you might need hp for is T9, and even then, it's more designed for you to boost your max hp with Stoneskin/Succor. Unless you NEED the extra hp, the extra is useless. Think of it this way - you sacrificed 100 hp per heal to get 450 hp you probably aren't using. The only hit point that matters is the last one. And that 100 hp per heal is also 75 per Adloquium + 75 more shield, or 110 hp + 225 shield on crit, or 400 hp + 400 shield divided amongst the raid for Succor, or 60 hp on your faerie's Embrace, or Whispering Dawn, or more potency on your DoTs when you throw them out, etc. That's a lot to give up for no real benefit.
