ranked is empty, but in my opinion it is by far the best setup of all the player options. I dont know what truskill is or how its calculated, but the way ranked is set up is just vastly superior IMO.
you dont need a room full of good connections, you just find one opponent who has a good connection(in case you dont know ranked rooms size is maxed at 2 people)
you dont have to worry about some idiot with a red bar coming in and messing the room up for everybody else, if a red bar enters and hits ready just find another room.
you dont have to sit and watch for 5-20 minutes before playing, just enter the room and fight.
when you do find someone good you can play eachother for as long as the 2 of you like without having to worry about playing 2-4 new players between matches.
I dont know, maybe its just me but ranked is set up the best of all the KOF online modes yet people play it the least, are people still afraid of the word ranked because of street fighter? What am I missing here, how come more people dont just stick to ranked matches?
