Actually, I'd argue that because an RP is primarily interactive, making sure people can easily pick up on the interactive elements in your posts is beneficial for all parties. Most of these can be short and sweet, barely distracting from the atmosphere in a post. If this information is obstructed by flowery wording, that is a valid point of criticism. It means you either need to find balance or structure, not that you should let your writing style swing to one extreme of dull and clear or another of flowery and incomprehensible.
