Anyone else worried about the potential Revan/Nihilus?

Don't care for revan but my problem with him is he was both light and dark so how do you do that in game? Nuetral? Cause if that's that opens the floodgates for more neutrals, because why bother with a light side and dark side when you can just build one nuetral team for both? Unless they ban neutrals in which case you know someone will be p*****. And for nihilus they'd have to severely nerf his abilities to allow him to be balanced but I guess you can say that for palp and Yoda as well
