My ranking in Wild is 2404 and my ranking in Modern is 1710.
I played enough wild to max my league at Gold 3. I see maybe 10% level 4 summoners in wild compared to around 80% level 4 summoners in Modern battles.
I think Modern is starting to balance out today as I had a 10 run win streak. The level 4's have probably moved on up higher in the rankings.
