A personal preference list. This has absolutely nothing to do with how good they are, how relevant they are, how much people pick them, etc. This is really for myself.
Characters that I actively seek to play as.
Characters that I will choose depending on certain situations or moods.
Characters that I will occasionally choose to play.
Characters that I typically won't choose, but typically will enjoy playing.
Characters that I won't choose and will not typically find pleasure or great displeasure in playing.
Characters that I really dislike playing. I will note that this isn't fair to set and that I acknowledge that situationally these are all good/great characters. I just do not enjoy them at all.
