Given that I've fallen back on mostly playing the same character in these games for the most part, my problem is more of a sink-or-swim one. If I hit writer's block, I tend to get too overwhelmed by it and end up either bowing out or watching the RP die due to unwittingly contributing to inactivity.

It's important for me to focus. I tend to want to go to different things and try something else, like anyone does, but I also get my best results from just focusing on what I have. There have been a few characters I've thought about doing as my second, but none have appealed to me nearly as much as just trying to do the best I can with Batman. So I think you just gotta kinda feel out what seems right for you and do that.
