e.g. E7... 100% uptime for melees, but probably the most boring boss. Nothing is more boring than cuddling in the mid with the group and 123, 456, 123, 456.... No matter which melee you play there. Atleast the last phase brought something more to care about and some kind of movement.
About the "great" dungeons, they could atleast go ways other mmo´s did. Swtor for example hat bonus objectives/missions to do, which opened a secret path right before the endboss to beat an even stronger bonusboss with rare loot for crafting or pets, or even equip with 5 itemlevel more. Even those dungeonbosses had an enrage so you had to care for DPS. You could even use other special objectives when you´d crafter X on level Y to activate droids which help you, etc...
Dungeons here are pretty boring to play and to care there about to positionals is not really needed, unless you care about that 10s of your life. Even the pre 50 dungeons are more exiting with more passes, rooms, chests than any of the expansions. This 2 pack -> boss -> 2 pack -> boss -> 2 pack -> boss really needs to stop. It´s gameplay wise pretty stupid and it doesn´t help anyone to improve. I met enough monks who didn´t care about positionals and as i said something it was like "I don´t care" or "Yeah i know, but i´m pretty new and tired, whatever...".
And tbh... if we talk about monk only, i´m convinced that there are 2 kinds of players anyway. The minority which says from beginning "i´m going to play monk" or the majority, which won´t play monk seriously even without positionals.
It´s not "refuse" every time. It´s just no motivation to do better, to become better, whatever. It´s just not worth the time for such players, but they want their loot, no matter how. The great reason why goldsellers are a thing too.
FF14 is still a gear - related casual game. Just saying, healer LB3 ftw!
It´s just easier to complain in a forum than to learn a class or to kill a boss you know?!
