I will have to take some time to read the thread more thoroughly, but these have always been my thoughts when it came to player improvement: unless a person wants to improve, they will never improve. You cannot force someone to improve their play, just like you cannot force someone to care about whether or not they are wasting other people’s time. And that’s the reality of it all. I truly believe that the only ones who can change the “bad players” are the “bad players” themselves; no one else. If they lack said motivation to improve, you cannot force it to just manifest.
Maybe it would help to have a bit more challenge to content, but again, if people aren’t willing to rise to said challenge, then I’m afraid it won’t make much of a difference. I still remember all the cries for nerfs back when Weeping City first came out, and players wanted Ozma nerfed (and I think Forgall as well). And Final Steps of Faith. Weeping City and Final Steps were actually challenging content, at least compared to previous 24-mans and MSQ trials. But people didn’t want to put forth effort to improve; instead, they would rather it be nerfed. Perhaps I’m a bit jaded, but I think that’s what would happen if the devs did add in more challenging MSQ/midcore content. People who don’t want to rise the the challenge simply won’t; they’ll just cry about it...
Instead, I try to spend my time playing with friends as opposed to randoms. I tend to stay silent in duties, because I have gotten tired of being called “rude” or “an elitist” for just telling someone something basic like “AOE large pulls; you do more damage” or “Try to refresh Straight Shot every 30 seconds for a critical hit buff; Bards love crit and you’ll get tons of procs during your songs that way”. So, I generally do not give advice anymore. I have a hard time staying silent when people are being outright hostile in chat because that gets us nowhere, and is just a waste of time; and I do have a difficult time not telling DPS to AOE, though I just bite my tongue anymore to avoid confrontation, because they immediately get defensive and hostile about it. Of course, people get hostile about anything. Last person I had get that way was a NIN in Temple of the Fist who died because they stood in AOEs, and then called me a “shit mentor” for not healing them in time even though I tried to Benediction them (but, of course, Bene delay, and it went off on me instead). Well, try avoiding the pretty orange circles on the grounds next time, sweetheart.
Truth be told, maybe I’m just a bit too old for confrontations like that anymore.
