most people volunteering for this game arent really doing it to "grow" tf2 but rather out of passion. some people grind dm, mge 24/7 and map talk like fuck to get to prem and some cast, produce, set up cups and run leagues. most people who quit tend to leave it to someone who is capable to run X, Y or Z and not turn into what doughy is describing.
i can only speak as a very inept caster and sorta for casting (very low effort compared to producing) that if you dont enjoy what youre doing and on top of that "hate" you will get just makes you grow colder towards this video game. burn out is pretty bad especially for something you are passionate about but there's a time where you just need to let go. think this was me just rambling about how i felt (see: making this about you above (big ego))
