I actually had this exact experience once in ff11. Abyssea just dropped and people dropped the group/ camp play style and doing story as you go to leech to cap and solo the story. I didnt want to play like that, but the meta was leech to cap... solo story. When i tried joining LS to find ppl to play with i was told leech to cap/ solo story.
when stuff is the meta , it is considered law. Like currently the meta is pull big regardless. In my first dungeon as a fresh tank, a healer tried pressuring me to pull more then i was ok with. I even asked him to stop, he tried to pick a fight. I felt i had to leave, as i was what the group wanted.
If you make something optional... people will choose to skip it, and not touch it. Leaving those who do want to engage SoL. ff14 has group story content, such as dungeons and trials. how do we put booties in seats if it is optional and people skip it.
ALSO. the 1-50 content from what i notice is a tutorial. it teaches you stuff you can do in game, like leve quests, trials, dungeons, grand company, job quests etc. I wish hall of novice wasnt optional.. as people skip it, and end up not understanding their party role. Bad enough people treat group mates like npc.
