if you want to have your guitar stay in C forever more, then take it to a tech, and have it set-up in C. if not, then, as I said, going into drop C won't kill your guitar, but switching back and forth really often between E and C could cause some stress on the truss rod.. I think that as long as you don't switch back and forth 10 times a day, then it should be fine, but it won't perform it's best when in C.
