The main reason I want New Game+

Actually, with the removal of Energy Drain and Lucid giving, what was it, 2-2.4K mana; I'm also worried for SCH (and maybe AST too) running out of mana by the time they reach that phase. Imagine having to sit around for 30 seconds dodging mechanics to get mana back because you used it all DPSing just so you could get to that point in the first place. What a slap in the face that would be.

This post forgets something though: A player who gets to this point by the time New Game+ is out most likely also owns Shadowbringers, meaning their level cap is above 70. Meaning they are most likely going to be 71-73 by the time they get to this instance, which will do a good bit to increase their chances.

They're also very likely to be equipped with a full set of Scaevan gear at that point - and at very least will have received Ryumaku gear from the patch quests, assuming they keep the same pattern of giveaways for 'old' expansions.

To go into the last Zenos duty at minimum ilvl as SCH and see if it's even possible to DPS down the 3 swords only using Bio II and Broil II. Just want to make sure they are not gating new healers with their "new healer friendly" changes.

ShB Bio II is only slightly weaker then Miasma +Bio II, and combined with the fact not only Broil II is stronger but you are casting more of them with not having to reapply your dots as frequently, I say you'll be fine.

Yeah, some people really are overstating the DPS loss of SCH there... if ASTs can do as they are now, SCHs will be able to as well since they are still stronger in the DPS department. Also, as others stated, the Echo exists in this kind of trials, so you will clear it eventually.

You need to consider the bigger picture though. If you come in this instance with min iLvl, it's your choice not to have geared up in whichever way the game is offering you all along. You have a dungeon that give 375 iLvl gear, tomestones accumulating for iLvl 390 gear, raids for 380 gear, 24 man raid for 390 and upgrading 390 into 400...
Don't try to sneak some consideration on general healer balance out of this particular restricted self challenge.
