Looking at the new PBE changes, I can say nothing more than that I am extremely proud of Riot and I hope they continue to slowly and steadily take this direction.
What I mean is there is not a single damage increase on the PBE; every champion listed has had their damage lowered, and where there is a base damage increase the ratio was subsequently lowered. This is only one patch, but I am hopeful this is a sign of Riot making an attempt to steadily creep their damage down.
Of course, if Riot slowly lowers damage it will push the champions with lower damage out of meta until all damage is lowered, but it's a small price to pay for the game to go back to its former glory.
Or it could just be me getting my hopes up, but we won't know until later.
