Excited for new rune/mastery system, But concerned about balance of champions

i am VERY excited for the new runes and masteries.. but i know all too well what happens when riot changes one and ignores a champion that uses it..

the example i am using hit me very close to home and that was the complete and utter, and yet entirely indirect gutting of nidalee in patch 6.22 Although did receive a minor (and near negligible) nerfs the patch right beofe the preason (6.21).. the preseason change of the removal of "strength of the ages" is what dropped her winrate by 8%.

every nidalee that had been running thunderlords prior to pre-season had an 8% lower winrate than those who ran strength of ages.. so when EVERY nidalee was suddenly forced to run thunderlords her winrate dropped by 8%.. this is a obviously and and predictable change and i told riot about OVER A MONTH before the strength of ages was removed... and yet nothing was done.

i am using this as an example because when the runes and masteries are changed.. there isn't going to BE an "easy" and "obvious" change in winrate like there was for nidalee. in pre-season 7. champions that receive a nerf or buff from these changes are going to have no point of reference, as you can't simply remove runes and masteries before hand to get that data

so PLEASE spend the time to test EVERY champion. and PLEASE consult the experts of each champions.

last pre-season change with the removal of strength of ages was done very poorly even with a blatantly obvious "tell" of how it would gut nidalee and other nidalee player besides myself also pointed this out to riot.

PLEASE listen to player during the re-work of the rune and mastery system.. if there IS a "tell" its not going to be as easy or as obvious what happened to nid.. and considering that was missed, i hope you spend a LOT more time looking into how these changes are going to affect each champsion..

i do NOT think you have the man power to test EVERY single champion and i highly doubt each tester will have the mastery of every champion that is needed to test this.. so PLEASE consult your playerbase..

put this on PBE a good 1-2 months before hand to test BALANCE and not just bugs.

I'm sure I'm preaching to the choir when i say this, but this is a HUGE overhaul that is MASSIVELY going to affect balance, so PLEASE consult the players on how their champion will be affected.

no matter how good your balance team is... you're not going to know each champion like the players who have played them 1000+ times.
