WHile you are being sarcastic, the "You dont pay my sub" defense is more common than you think.
Just last night i did my Expert Roulette as Sage and landed in the 90 MSQ dungeon. 6 minute elapse, standing at the first boss (A very common occurence).
All 3 members of the party failed mechanics over and over, which caused me no small amount of stress keeping them alive.
On the second boss, the Reaper was offered a tip on upcoming mechanics of the boss to watch out for and was told "Chill i wanna do this totally blind"
And proceeded to mess up mechanic after mechanic.
On the final boss, he managed to get Doomed 3 times, drawing ALL of my resources to keep him alive while the other 2 continued to fail mechanics, leading to all 3 of them being dead at one point.
The Reaper demanding to do a blind run directly led to the Tank's death, which in turn led to the other DPS being killed by the boss when the Tank went down.
To that Reaper and ALL others who proclaim "You dont pay my sub"
This is a god damn team game. If you're unwilling to work as a team, don't force your poor decisions onto people who have to deal with the mess you create due to your inability to play nicely with a group.
Trust is perfect for doing blind runs where available. Dont make other people miserable for your own selfish reasons.
Trust NPCs in dungeons execute all mechanics properly outside of some scripted "accidents" due to AI personality quirks.
You can quite literally just follow the NPCs around for the whole fight and win even without understanding the reason why the NPCs are doing what they're doing.
The NPCs literally guide you through the mechanics. There is no reason for someone to fail endlessly in a Trust run outside of a sheer refusal to take notice of their surroundings.
