no, lol.

You can [i]try[/i] to abolish character sheets in a roleplay and see how well that turns out, but CSes are a shitload more than just writing barometres. They give both the writer and the GM an idea of what kind of character you intend to play. I can't just go off someone's writing level to know whether or not they're a good fit for the RP- some people with not so great grammar can still be great in a roleplay because they're a joy to have around. What it comes down to is seeing how much their intended character fits the setting- not what kind of writing they have.

CSes are a baseline pitch to work off of. If the GM likes your pitch- congrats, you can play said pitch. The character will naturally grow and look different from said pitch as the RP progresses and that ain't a bad thing- but you need that initial groundwork to build on to begin with. Abolishing all CSes is a terrible idea because if you don't know who you're RPing with, even with a writing sample, RPing will be even more of a crapshoot. This method only works with friends you trust- and even then I'd still vet them to see if they really made a character fit for the setting.
