PBE, and improvement ideas

The pbe is as we all know is the public beta environment where we get to test changes early and report bugs so we get the best launch possible when the live date hits, duh right ? To be completely honest am a bit disappointed that riot doesn't experiment more with it, feels like alot of potential is lost and ideas that just sit on the shelf because of fear, PBE should ideally be immune to this, its a testing ground getting players to, well playtest. for example the riven edge rework, jinx w criting the grasp rework we recently had there isn't really enough out there, the pbe isn't suppose to be balanced so if a change like that happens you can report it and say oh well get rid of it but we learned something right? To have more change in general could find solutions to problems with champs that are not just full reworks and redesign like making talisman give starting ap and only build into runic echos and cinder while machete has its attack-speed only building into warrior and razor, be honest how many ad jungles wont go for machete. its sad to see it played so safe when theirs a lot of potential.

TLDR, Lets try some new shit on pbe!
