One of my fondest gaming memories was back in 2006/7 trying to conquer the Cave of Ordeals in Twilight Princess, and more recently conquering the Treacherous Tower in A Link Between Worlds both on Hero Mode. There's something about a 'wave mode' that appeals to me - and the difficulty of it.

For those that don't know, they're basically dungeons where you face one wave of enemies at a time - Wave 1 is extremely easy and Wave 50 isn't easy at all.

It could be pretty fun and unique if the Dev team here at FFXIV could incorporate some kind of similar system as an alternate way of earning loot and bragging rights over a server. There's plenty of opportunity here to be creative, and if there's no weekly lockout, could be something quite a lot of people could enjoy purely as a mini-game.
