I say a definit no to this...
it is totally unfair to do so, if someone chooses to delevel using their stamina to do so, why would they have to be punished for it..also what if they are deleveled due to bounties that would make it even worse if they then were not even able to level up on the map they are on already..
fair enough if you leave the map you can not reenter until you are correct level, but as long as you are on the map with that said creature you should be able to kill it...
like someone also mentioned before ..if at EOC, it might be just as much fun to delevel to keep playing, as just sat letting stamina overflow..
also poll is wrong..why do we have to choose an option for levels when one is against it in the first place
