@Meddler Have you ever considered having champions with 2 personas via balance changes
What i mean is that champions currently oppressing higher elos or LCS would have they're own tune of nerfs and buffs, but the same champions would actually have ANOTHER persona or w.e in lower elos so you would have :
LCS tuned Jinx
Regular tuned Jinx
Hope you understand what im getting at now. This might sound like more work for the balance team but might actually lead to a overall balance satisfaction among everyone. You could tweak champions oppressing lower elo and balance around that elo while at the same time the same champion would be tuned different in much higher elo or LCS.
