EV and KP HM are for people with mostly columi, but you can easily have some lower than columi too in the mix (they do drop some columi equivalent gear in addition to the rakata stuff)
EC SM originally I would have recommended full columi + at least some items higher than columi, but it has been nerfed and made easier than it originally was.
TFB SM is technically tuned for columi gear, although you need good group to do it with just that.
Thanks for the response. So I just looked at SM TFB and it looks like it drops all Rakata as well. Would I still be under geared for that?
Those rakata drops are supposed to be upgrades to people doing it, so you are supposed to be able to do it with the gear tier just below rakata, which is columi.
