If the balance team wrote a letter...

It would look something like this: Hey guys, Are you tired of not having lee sin in all of your games? No? Well we sure were, that's why we're buffing him while he's already strong! And if that's not enough we're buffing zed...again, next patch! Don't you love being one shot by zed? Here at Riot games, we love seeing the same champions picked over and over again in the LCS, so to promote more strategic diversity we're bringing the same champions to your solo que games. But don't freak out, it's on the PBE, and is subject to change, and we'd like to hear your feedback so we can totally ignore it and shove it down your throat anyway! Riven and Vayne stomping solo que? It's okay, we're nerfing shen and maokai. Have Fun!!
