I am one of the people who wants more focus on tactical healing. FFXIV is one of the few mmos I don't heal in because healers are just DPS with very simple rotations and a minor extra job where you don't need to think that much because everyone has nearly every kind of heal (burst, aoe, mana efficient HoT, ect), a ton of mana, and only 1 person is generally taking damage over time outside of aoe burst windows so you don't need to manage more than one HP window outside of specific events.

Statics may be different, but getting to statics takes forever. The only healer that had much going on in terms of mental effort to heal well was Astro, and that was due to Essential Dignity and Lightspeed being very interesting limited healer resources, not cards.

It seems like they are tipping the scales more towards wow style healing where healers are more focused on healing. Maybe it will be good, maybe it will suck (there is a real danger it won't actually be about tactical CD and mana management and just be 'mash your heal instead of dps' which would indeed be worse) but the idea no one wanted healer to focus less on DPS is an overt lie. A lot of people don't heal because healers are basically dps for most content and don't bring the things they like about healers from other mmos to the table.

You should do things that make you happy. I recommend against reactionary compulsive anger, its bad for you. If you are LEGITIMATELY worried rather than reactionary (ex: you actually read all the abilities rather than listened to a hot take and paniced) by all means sign the boycott, I think you deserve support and respect even if we don't agree, and at least one healer should stick about giving you what you want! Like maybe a healer that gets heals from a dps style offensive rotation that get stronger the better executed the rotation is!

But it is worrying some people are super mentally engaged with the thread and are actively throwing themselves into something upsetting them and seem to be looking to maximize the mental energy they commit to being upset.
