lol yea kiriha won 1st place before scouter update but he didn't faced any sk (the OP class) in his run, you should also mention this...
anyway yes old scouter system was better, there was more strategy and more gear to worry about, but since they are using the latest game version I don't know if would be possibile to reuse it
PS: even the old pet system was better especially because of the pet's drop bag
