I'm not for or against the widespread use of parsers and cannot conform or deny whether I use them myself on certain content but I can give you an easy argument against personal parsers. I'm not sure why you think personal parsers are the answer because the argument against them is so simple: There is NO SUCH THING. A personal parser stop being personal the moment it is introduced into the game. Want to know how? "send us a SS of your parse or kick" or the like. Yes, you can do this on PS4 at the very least using a screenshot sent to another PS4 user.
So as soon as any kind of parser is introduced into the game they can and will be abused in negative ways. I play on PC so it doesn't matter at all to me, but yes. An easy argument can be made to dismantle the "personal parser" idea, but like I said, I don't care either way.
