Qarn Hard final boss seems WAY overtuned.

[Snugglebutt]

In my first run (in duty finder) we killed this on our first try, and all of us got too many stacks at least once and had to wait to be released (two people got it twice I believe).

Seems a bit too easy if anything, considering nobody has any substantial poetry/final coil gear yet.

It's not too easy, it's actually about right. It's called hard mode not extreme mode of which it is on par with what the middle level of difficulty between easy/hard and extreme should be. It shouldn't need poetic gear or end game raid gear to do a hard mode 4 man dungeon. Those sort of gears are for extreme mode trials plus end game raids.
