1. Even though there are generally accepted rules, there are gray areas (what constitutes overly defensive play for example) which make it very hard to mediate fairly.
2.If you solve the first problem, there is always cheating to be taken into consideration. While blatant AA/TMC is obvious, it can almost be impossible to tell if someone bumps up their fhr by a single frame. Experts can often tell but they have to be the ones dueling, it's basically impossible to detect from a third person perspective.
3.The amount of whining would be OVER 9000!!!!!!
4.Most of the trusted/mediated that already exist on the site don't play d2 or are horrid duelers~
I love ft5 wagers, but I can't ever see them being mediated by jsp
