Anime that NEED Another Season ?

I'd be pretty stoked if Fullmetal got another season though I feel both the original and brotherhood did a nice job tying things up... I know Berserk had that remake but I've only seen the original and that show NEEDED another season. It ends in the worst possible way; with your jaw on the floor and any hope of resolution shattered.

Guin Saga Attack on Titan will get one next year I believe, don't worry.

I've never been able to accept the fact that Ouran High School Host Club ended. Just one more season pls I will sell my car. Okay no I won't, but still!

Noragami is already getting a new season later this year. September I think? http://img00.deviantart.net/d485/i/2013/148/c/7/elfen_lied_rising__revengeance_of_mistralucy_by_pyrolover90-d5sbsfn.png For me, I would like a second season of Elfen Lied with the original director. There is still a lot that can be explored about vectors, diclonius and the like, and we could possibly see it from the perspective of another diclonius who has to decide between stopping Lucy or helping her wipe out humanity. Such a rich world that you can get a second season out of.
