How do you play SCH in PVP.

[Sylkis]

Always be buffing! If you're not healing, you're casting Protect, Stoneskin or Adlo. This is doubly true for yourself, since even with VIT accessories, a melee LB can take you down quick. Any time you finish a skirmish, the first thing you want to do is refresh Stoneskin. Don't forget to cast it on your fairy, too!

I disagree with this one, first of all def/mdef (and thus protect) does not affect pvp. It gives you a buffer against MNK's mass buff removal but no one plays MNK. Throw away protect and put blizzard II and surecast on your pvp bar.
Time is better spent on watching map/throwing miasma on targets

For OP:

Eating your fairy for aetherflow stacks -> lustrate is quite useful in contrast to pve. Your fairy is bad at healing moving targets (you).

The VIT (and any other stat) PVP skills give too little return for their cost. Instead, use more vit accessories.

There may be a reason why you get targeted often - are you on the edge of your party (front, and left/right side is vulnerable to tab target)?

You can choose to be out of sight - this can be as simple as not using flashy mounts or wearing flashy gear, hiding behind rocks or on high points, standing at the centre/back of your party etc.
You can also choose to be targeted - wear lots of VIT accessories and have ~11-13k HP and it will be a lot harder for you to die. The healing potency loss isn't too bad (~10-20%) although I think it affects sch more than other healers. Upgrade purify, attunement, aura blast (don't upgrade damage), focalization (potency), aetheric burst. Probably in that order.

Survival tactics:
Sprint and Line of sight behind rocks or up stairs -> Adlo
Surecast -> Adlo
Equilibrium -> Adlo spam and blizzard II on last cast
Swiftcast -> Adlo
Run to a choke point such as stairs and run back toward the enemy, Swiftcast -> Blizzard II
Lustrate Lustrate Lustrate Aetherflow Lustrate Lustrate Lustrate Dissipation Lustrate Lustrate Lustrate

Fair enough. I've long wondered about Protect. I thought it didn't work in PVP, but then I always saw people casting anyway, so I figured I must've been wrong. I'll gladly put on another Equanimity and/or an AoE root instead.

I'm mostly referring to non-combat time. Far too many healers spend off time standing around like morons instead of refreshing buffs. It's easy enough to keep track of the map while getting Stoneskin on everyone around you.
In combat, definitely throw out your DoTs, so long as everyone around you (including people not in your party) is in no danger.

For trying to survive or escape this is what I do:

1. Place fairy with Stay, Sustain
2. Change to Obey
3. Spam Embrace and everything else when possible
4. Run around the fairy, not away. But, keep moving always and in a big circle.
5. Aldo and Eye for an Eye on fairy, then Deployment Tactics
6. Pop cds as needed. I save Swiftcast for Emergency Tactics and Aldo.

Some DPS might insist on killing the fairy first, if they do, keep moving the fairy. The trick is to keep placing that fairy and running around it. You can also Attune and let it heal you for a while. Always have Stoneskin up before any encounters. Dissipation is awesome in PvP. I also use all but one Vit accessories, and maxed out Vit in PvP attributes. Usually DPS get tired of chasing me or I make it to my party.
