idea for next dungeon

i think we need old style ff dugeon.it would be great if there is a dungeon with many dead end on it (without mapping system of course) and optional boss that harder than main boss(equal as extreme tiral difficulty maybe?).party need to trigger optional boss first(or completely random) and we need to kill without wipe so when party wipe,the optional boss will gone too.

the reward for kill the optional boss is gear ilv 5 under from current savage gear(ilv 365)

ps :Sorry for bad english:(
