Personally, I love the idea from some players that 'healer strike is pointless, because I'll just play healer myself if the queue times are too long'. Because, let's say you're playing a tank or DPS through the story. You get to the final level 100 trial, and the queue won't pop because there's no healers (due to combination of this and VPR/PCT hype). So you swap to a healer to get a fast queue... which healer, exactly? You'll all have used a non-healer to do the story, so your healers will all still be at level 90. The idea that people will just casually swap to a healer to avoid the long queues is wishful thinking, only SMNs will be able to do this on release. Of course it'll be less of an issue after the first week or so, when people start levelling secondary classes, but it's the first week that this strike aims to impact the hardest anyway
Already do Savage week 1, and I've done Ultimates as a healer (even on-content Ultimates, not just outdated UCOB/UWU). What more can I do? And besides, as mentioned a million times, I still have to do things like EX roulette/Hunt Trains to cap my tomes. My job should feel fun to play in that content too. Or are you really trying to take the stance that 'your job should only feel fun to play in 5 pieces of content per 8 months, and nowhere else'

On the subject of Cleric Stance, I think it'd be good to bring back a stance-dance optimization tool on one of the healers, but not all of them. I think SCH is the best candidate for it, and this is how I'd do it:
Strategy: Offensive, increasing the base potency of Bio (30s), Miasma (24s), and Shadowflare (15s) by 20p. Every healing tool works mostly as it currently does while in Offensive stance, so 'locking yourself in stance' doesn't punish you with 'your healing is pathetic'.
Strategy: Defensive, adding additional defensive properties to actions. Turns Physick into Adlo (saves a hotbar space), Enthuse (new basic AOE heal GCD) into Succor, adds a barrier to Excog upon application, changes Indom to a barrier, Expedient's mitigation increased from 10% to 15%, Protraction applying a second copy of itself, Perpetuation, for another 10% Max HP increase effect, etc.
Strategy: Emergency, increasing the healing power of actions, at the cost of removing their defensive aspects. For example, Indom is increased potency, Excog heals on application as well as via the buff, Enthuse/Physick heal for 2x as much, Expedient's sprint duration increased to 15s, Protraction healing on application, etc.
For those that don't care to optimize anything, they could just stay in Defensive and everything (mostly) works as normal, with some bonus potencies on their barrier effects compared to now. For those that do want to optimize, they'd want to swap to Offensive every time they have to refresh their DOTs (a total of 17 per 2min), and swap to use Defensive or Emergency to get a slight bonus on their healing tools, depending on the situation. For example, swapping to Defensive to use Excog and get a Galvanize barrier from it, then using Deployment Tactics to spread both the Galvanize, and the Excog effect. Also the fairy's Embrace and Fey Blessing actions would be modified based on your selected stance, to make it feel like you're an actual duo, instead of the fairy feeling like little more than 'a permanent regen'.
