I... kinda relate on Bobby66 a lot on that specific circumstance.

It's not the norm, but when it happens, it's very frustrating when all we wanted is to communicate so we can ensure a better chance to complete the duty. Silence is not equal to trolling, not participating, that's true. But it's also not equal to participating and cooperating. It's up in the air. Each wipes contributes to the tension and that silence can be taken the wrong way, just as a poor communication can do. These wipes can happen even in normal contents.

Try getting 1-2 silent DPSes that does not focus the adds in correct order in Innocence Normal without shield healers. (you will die to excessive slash resistance debuff)
Try getting unresponsive tanks who do not perform LB3 to get through a12n, Endsinger, and/or Seat of Sacrifice. (you will die to their ultimate raidwide)
Try getting muted tanks that had no clue which add they needed to grab attention from in Titania Normal.

Maybe they don't respond but somehow do it correctly at next attempt? Great! Bravado! But what if they attempt the same approach and wiped the party again (and again) with no sign of response and/or improvements? At that point it's either vote to dismiss, or use the door yourselves.
