Do you play multiple characters at once or switch between several different characters? What do you like most/least about playing multiple characters?

I prefer having two characters logged in at the same time. Usually they are working together but sometimes they adventuring in two different locations.

I like being able to mix things up a bit. If I constantly just play one character it starts to feel very repetitive clicking hotkeys and casting the same spells over and over again.

I hate when friends want me to play one character over the other. I play characters based on my mood!
