First thing to mention, I'm more of a crafter than a combatant. My experience with dungeons and primals has been minimal at best and usually reluctant at that. Just wish to get my relic weapon and be able to help friends get theirs. Gear and my stats listed at bottom of post post-edit.

Does anyone have any SCH advice for Titan HM?

I've not tried that fight yet but will soon and am a bit nervous after hearing it's a big step up from the other HM primals. I'm also worried about lag, as I'm Australian playing on a EU server.

Should I be moving constantly to pre-empt every skill he uses, regardless of target? I'm worried that might mean I can't cast as much as will be needed, but at the same time I don't want lag to mean it's too late to get out of the way of things aimed in my direction if he does choose to target me.

I'm already trying to learn the rotations of skills listed in various guides (although it's been difficult finding a recent SCH POV guide, the stuff I'm relying on came out last year).

What I'm seeing is to mainly focus on Galvanise related spells and other general damage mitigation, not so much healing directly, and to keep Eos off the edge of the field (?) when possible while spamming constant free fairy heals. Virus when possible or just before big damage, Sacred Soil and Succor just before jumps, Adloq always on tank, fairly typical stuff.

What I'm mainly concerned about is if I should be running around constantly to combat lag and sacrificing spells to all the interruptions that would cause, or not, or how to balance those sorts of things throughout the fight.

Oh, and one other thing the guides I've read haven't been clear on is if I should go full time DPS during Heart phase or not. As a SCH, which is generally more valuable to the group between CS+debuffs+Ruins or heals+buffs during Heart phase?
