I give this idea my support. I found it really annoying when I lost around 10 levels because of accidentally ranking down.
Support. I've had this happen to me before, and it's really annoying. De-ranking should have a confirm command. --- To anyone that thinks this isn't necessary because it's "common knowledge" to not click the sign after you rank up... Not everyone knows it resets you to that level again. Also, even for people that do know, clicking the sign at the end may be accidental, so this would be a great addition for everyone, especially people that enjoy re-playing previous levels.
