truth be told, they aren't demanding.
1-31 requires you to smash buttons
32-50 additionally requires to move out of (sometimes not indicated) AoEs
lv 50 duties are the same BUT you can utterly overgear them so that it returns to the 1-31 tier of content
Then comes SoF, the one duty where you actually have to play as a team to succeed. Where you are actually FORCED to play the basics of a MMO.
Want to blame the team on something ? Blame them for making idiot-proof content all the way up (even though Titan when i70 was a thing was pretty hard), not because they actually made a fight corresponding to the genre of the game.
Enough idiot proof content. Force people to get better at their job to progress. That's already a solo player game's mechanic, why can't it be applied in a MMO ?
