Create your own Boss Fight/Mechanics

So I thought this would be interesting! Lets make our own boss fights or interesting mechanics that you would want to deal with, maybe we'll even see a few implemented in future content bosses if they are interesting enough :D

I would like a mechanic where the boss spawns zombie adds and their auto attacks inflict zombie status effect on you. Zombie effect can be cleansed. Any healing done to a target inflicted by the zombie status will result in damage instead. The boss will perform a megadeath attack few moments after the zombie adds are summoned and anyone not inflicted by zombie status will instantly die. This is exactly the same as the Yunalesca fight mechanic in FFX and I thought that was very interesting and would love to deal with such a mechanic in FFXIV :)
