In my opinion if you need to wait until your opponent roleplays in order to give you roleplaying material your rp is ten times weaker than the guy who posted before you. And it especially doesn't work if you don't take into account "Hey, maybe that guy is waiting for ME to roleplay as well before HE roleplays".
I've been in feds like that. Where one guy posts an rp 2 hours before deadline and the other guy is complaining that he only has 90 minutes to write a roleplay now.
Also, the excuse that its the only available day that someone can rp that just happens to be on the deadline is also bogus. Because if the deadline was changed then would somehow miraculously find time to change their schedules as to post on THAT day instead.
But meh, it's just how some people play the game. I play it to have fun at this point. I've already had all the accolades I could wish for. I don't need to play dirty.
