Really? Most questions I had in the 80's, 90's and 2000s were about rules, how to make good tournament adventures and surprisingly when to stop a campaign as many had trouble playing in the high levels. Yes I had some questions about player management but not to the degree I see these days.It was probably the single most common question I saw back even in the OD&D days. Player/GM conflicts have been an issue since day one.
And yes conflicts have been there since the beginning but usually, it was about a ruling or a particular situation that often had nothing to do with the game itself but had everything to do about how to manage the table.
