The Final Fantasy series has built, through the years, a very specific list of "iconic buffs and debuffs" used in several games.

These include the Petrify / Stone, Poisoned, Confused, Berserk, and others.

So far, we have seen several of these debuffs (or variants) being used in ARR, in various locations.

Is there a chance you can build a raid boss centered around the Zombie debuff? This could need the healers to do "DPS" via heals in order to kill the boss, and the rest of the group could be temporarily granted a "Healing Stance" which would convert their attacks to heals.
