The ultimate problem isn't players not being open minded. Its just that people rather not waste more time than needed to a achieve something, be it menial tasks or large undertakings. For a game that is extremely math heavy and thoroughly explored by many veterans and people of many related professions its obvious to anyone that those who want to achieve things will go about it in the most effective manner in which others will follow be it by learning the job on their own(on of the best whms I've ever known did this) or through doing research(hey I aby burned blm and am perfectly capable of playing it not like an idiot wooooo).
What is hurting the game the most is how unfriendly the game is in regards to player error and length of time devoted to these events. Be it between gathering/planning people to do an event and then the event itself people do not want failure as it is a massive morale break and thus are willing to give up small bits of their own joy for the greater thus why people often say level another job.

Daemon people aren't smashing you for trying to invoke alternative play, they are doing so because you are advocating for them to do things that may ultimately burn them out as the game currently is in flux with many being unable to make the connections to do those earlier events and even then its a tasking choir.
