If you really have to buff Yasuo and Lee Sin before every Worlds ...

Maybe you really should make a pro-play only patch.

I usually think this is a stupid idea, but it would be very preferable to having some of the most annoying, and already popular champs buffed.

Consider how much damage it causes to solo queue, the experience most players have, when you let balance get polluted by your bias towards seeing specific champs in pro play.

I doubt pro players even want these changes but apparently their experience is decided by whatever you think viewers want, and that's bad too. But honestly if you really have to do it, only do it to them. Most of us just want to have fun in solo queue these days. One of the most frustrating things to see in patch notes or PBE is shit like +100% AD on Yasuo's R, or changes to Lee that make him even better at 100-0ing people. Like why? Who asked for this? These champs consistently pull insane popularity in solo queue and have extremely high potential when mastered, especially in solo queue.

So in conclusion any buffs for the sake of getting a champ to be picked in pro play, just because you think viewers like it, is bad. But if you really have to do it, don't make players suffer for it. Push numbers buffs only to a pro-only patch if you really have to do it.
