I mean, if it's absolutely necessary to the storyline, then okay, but . . . seriously? To me, the entire point of a roleplay is to play a role in a grand-scheme-of-things universe which generally involves the contribution of other creative minds. Just playing off a storyline by oneself with their own self-made characters (ESPECIALLY with others involved) is like . . . Just go write a novel.

I agree with you here, but I think my peeve with it leans more toward excessively long posts, no matter the amount of characters involved. I've seen some roleplays in my time that have players write posts that consist of thousands of words. What do they describe with those thousands of words? A scene where someone's drinking tea. 

Sure, I'm exaggerating a little, but you can see examples of what I mean when you read most collaborative posts.

I've also seen some really great collabs and posts which are no longer than four paragraphs. Really makes one think.
