What would it take to make you unsub from xiv

If the combat is just ShB V3.0, and maybe another decent MMORPG hitting the market.

I've already been picking up older MMOs to change things up since FFXIV's combat design is awful.

Continuation of the 2-minute meta will be the downfall of this game.

Considering only about 30% of the player base gets into content where the 2 minute meta matters, and the majority of JP players evidently prefer it, I don't think it will be the downfall of the game. The game would end up much less popular among the raiding crowd in NA and EU but others would still play.
