It will take some time, but I think that is a great idea. The only fighter I've ever been good at, I knew every single character in and out. Maybe I wasn't great with all of them, but I could use all of them and knew how they were supposed to be played and what they wanted to do. A game like MKX, however, learning every character and every variation of those characters is going to take A LOT of time. The reward will fit the time though, imo.
