str/cha Feca Duo for kolo and pvm

Hey guys I've been playing a str/cha Feca for awhile doing kolo and some random pvm with my guild but I want to make another char to duo with it preferably something that has a minimum amount of heals but can still do decent dmg. So far I've though about these options: int panda, omni eca, int enu, int cra. I'm not quite sure what would work well, but I do usually rush in kolo and have though about just going iop but that too boring for me. Let me know what you think.
