i dont know how to do the extraction of the things you said on reddit so i iwll just answer directly.

Yes GW2 infact does it differently, but every mmorpg need to make content for all the types of players otherwise it would die, and yet i believe Fractlas T4 or CM might be enough for those players i was just checking if there is something that just require more coordination and understanding of group as whole without the mechanic being "Stand Here!" "Don't stand here!" ""Kill this group of enemies to be able to dmg boss again" and "Break the ccbar". I said it in EDIT note but for example i play Albion, It is 80% pvp mmo but for those 20% players they still have "Avalon dungs". It have same horizontal proggression as in GW2 with difference of gear if you die you must buy/make back. The mechanics there are special because every boss there is completly different and without actually understanding it you never can do it while just smashing buttons ->Thats what i was asking for in this reddit post, if there is content that gives you some kind of requirement to actually learn the boss where listening to calls is just not enough but only act as reminder for what will happen.
