Bah, you're no fun. That's the kind of stuff that really opens you up to the expansive realms of anime and manga! Well, your loss. So you seem to be saying action/comedy/romance combination. I can't really think of anything off the top of my head that hasn't been mentioned...let's see what's down the list on Animesuki that I can recommend:
-Hey something from Gensou Maden Saiyuki should be good, though I didn't watch past the first season. That was action/comedy based on the Journey to the West story. Your usual kick-a** action.
-Rozen Maiden has action here and there, some comedy, some cutesyness, some goth-ness to it
-I hated Saishuu Heiki Kanojo, but you'll probably love it - boy meets girl, girl has to save world, their relationship gets torn apart in the process. Lots of action, lots of infidelity
-Shadow Skill was some kind of action/drama with lots of fighting
-Tales of Eternia had a totally rpg feel to it - action/comedy w/ sort of a love triangle going on
-Tsubasa Chronicle - you want it, you need it, cos it's CLAMP!! Totally action/comedy/romance (somewhat romance)
-Violinist of Hameln - action/drama - Brothers Grimm-like, maybe? Lots of action, music references, heaven vs. hell kinda
-xxxHolic - HELLO, CLAMP? Duh! Parallel to Tsubasa Chronicle - "Sliders" type of story with travel between worlds, lots of action, some comedy. You want it.
Hey, that was actually quite a few! Enjoy!
