The level of quality on these sprites is off the charts! I'm definitely hoping to see this pack being hosted on some servers in the future!
The only issue I have to report is that Sledge's infographic on your overview page lists his stats as 7s/6w, but when I tried him out ingame he was 8s/6w instead.
I've updated Sledge's info-graphic to match his in-game stats, which were the intended ones. Thanks for pointing it out for us.
