With things like third party DBMs coming to XIV... when are we getting addon support?

[Risvertasashi]

There are any number of things that could go horribly wrong. I think this possibility is being highly ignored.

Not entirely, there's been a little discussion about it in previous pages. For example, I would be OK with a read only API, and even if it's not read only, I definitely wouldn't want to see WoW-like healbotting. Also has been mentioned... healers and crafters (and people with tons of geared jobs) has been asking for UI accommodations since not long after release. The only healer topic SE has ever responded to, however, was the benediction animation one (and that was 'working as intended'). We can't count on SE to make these adjustments.

From a UI design perspective, there's also the problem of adding features that benefit one group, but only add complexity or clutter for another group. Allowing customization means much better QoL for people that can use it, while avoiding slightly worse QoL for people that don't.

Moreover, I don't think an overabundance of caution is a good reason to sink a feature with so much utility. We can learn from WoW's mistakes and do things better.
