What a lot of you seem to not understand about the PBE - It's not a testing ground for balance.
It's a testing ground for bugs/glitches.
Riot doesn't give the slightest shit what you guys have to say about changes they've made on the PBE. They're not testing the balance of the champions they're changing. They're pushing forward "The next patch" to make sure it doesn't break the game. Spaghetti code is a legitimate thing, and it's similar to the butterfly effect. Sometimes changing Sona's AD from 49 to 50 can cause a tool-tip bug to happen on Mundo.
They're not testing balance.
They're testing bugs.
: Fuckin Rito. Always trying to squash me on the PBE.
