It's not possible due to rito's encrypted codes, that's why you get low fps on ext overlay when you use farm keys, back in time it was stable, but not any more. There's no solution for it. I highly doubt anyone can code something better than GGorbwalker. Also the ADCs are perfectly fine as orbwalker wise, only last hitting is not that good which you can handle If you know how to play ADC anyway. I am not here to blame anyone neither but I know people who reached to grandmaster/challenger with EXT, I even reached to diamond as a bad player at leage of legends so, I get your point but it's how external works, and it's good enough to carry games if you know how to play. And sadly that farming issue has nothing to do with GGorbwalker's code or improving something, gamsteron is a good developer already but the issue is rito and what they give us to access and make them work in EXT.
