Do you do this?

So do you jump on the doll here and on the lights on SG or not?

I was just wondering how hard is to jump there so i tried and jumped back down when time showed up, so there would be just one winner (it was I).

On SG map i dont jump there because one dodgeball or fireworks is game over.

What do you thing? Is it fair play? Is it bug? Should it be banned or is a person there too much of a sitting duck and easy target, that it should be allowed?
