I'm not worried about Pokemon like Ferrothorn getting worse. I'm worried about Pokemon like Kyurem-B getting better. Game Freak have, in my mind, already done a great job of trying to balance the game with generation 6 - sure it isn't perfect, but I'm optimistic things will be significantly better that they were at the end of gen 5. Why undermine their work to balance things a little more in favour of defensive teams by giving offensive Pokemon a blanket buff? I just can't see any concievable way that setting levels to 50 will result in a more desirable metagame - offense doesn't need to be any better - and the only way I feel a change like this should be justified is with the conviction that it might feasibly result in a more desirable metagame, and I can't any way that making our metagame more offensively-inclined, or alternatively banning several more Pokemon is going to make the game more fun. I can't see how the minicule advantages of this change outweight the clear negatives resulting from the way things work at a lower level.
