Hello,Im looking for dramatic action manga.Mangas like Fullmetal Alchemist and World Embryo that have some light comedy together with the drama are welcome as well.Sorry for the bad english and thx in advance

perhaps Hoshi no Samidare-- i find the art to be pretty bad and the premise to be pretty ridiculous but its got really good characters, like they are all fleshed out really well with their own agendas etc. People do die and its not like the good guys never die and the hero in this manga is definetly not your typical hero.

also would suggest

Dance in the Vampire Bund--has a different take on the whole vampire thing. its quite dark though but its got good romance, nice action and excellent art and OK plot.

Angel Beats--best anime of the 2010 spring season

lol it like you read my thought. lately I've been really into these kind of manga, so I've been searching, anyways.
