I think part of the problem is people take on too many lines and get spread too thin. Inevitably we all have one or two lines that are our favorites, and usually (not always) they get a little more attention than the others. Add to that RL life drama/crap/issues/whatever and when people do get online they only want to play those one or two lines. I think they like all their lines and will say, 'oh yes, yes, I really like the line and want to keep it', but as happens all too often the other lines get ignored or pushed aside. I've seen it happen. I've been there. It's hard to keep up with multiple lines. I don't care how good someone thinks they are.
