Worth Ditching my Mainstays?

[FlapJack]

Hey all, I'm new


Well...here's the deal, I play City of Heroes...but for some reason after the past almost 7 months it has seemed to have gotten old for me. The question is, should I ditch this for PlanetSide? I've tried WoW, and personally, I hated it. I've played other free MMO's like Silkroad Online and Rappelz but City of Heroes is the only thing I kept playing. Now it's getting somewhat old and PlanetSide just looks fun...would it be a worthwhile investment for me to order this? Any tips, comments or suggestions?

Also, would I still be able to play if I just bought PlanetSide and not Core Combat or AfterShock or whatever it is? Do I have to have these to play?

Thanks,
