Generally speaking you should always keep your original name no matter how bad you think it is, because from what I've seen after someone gets a namechange to something they think they want, it ends up being worse. If you really think you must change your name, find an old game you like and name yourself something after that, or something you will always like for a long time. That way you aren't changing it to look cooler to everyone else, you're changing it because you like it.
