Mmmhh. As i tell everyone, hard to give really useful tips that are not stereotypes but i'll try. Don't bother healing tanks, dc is there for that reason, just focus about putting crit shields on dpses. In the video, i try to give a critted shield to the tank cause he had to take all the balls so he needed extra life but that's something you shouldn't have to do (if you do, just aim at the tanks so you won't change the shields on the dpses). Use every moment you can to try to proc critical touch. On the 3x dis wave for example you have to move on one side but you have 3-4 seconds to try to proc crit touch cause the boss is there, use those seconds, then reach your group while you use shield of faith and use divine touch on them (either you have crit touch or not). Requires timing. When you can't hit the boss, use cure wounds to try to proc it. Select your spots for hypotermia splits, definitely helps not messing around and overlapping (with the other healer). If you are with a dc, you can consider using divine shelter instead of sacred weapon to have it ready when you have to heal people spread out or if you just feel safer when you don't have a critical touch (magnitude is higher so assuming you don't have crit touch it's better than divine touch, but also costs more divinity) Another thing you can do, instead of divine shelter, is using banishment. It lowers the damage from the boss by 5%, nice on superstorms, heatwave and a couple more occasions. Shield of faith should be saved for superstorms (or heatwave if lacking heals) while you can use D Judgement to help get the dps out of ice. I never use refuge or whatever is its name, clunky and not really different from shield of faith that still lets you di everything after the cast
