Examples when you try to explain content for those newer in 24 mans:
  • This is so easy it doesn't matter.
  • You can just forget mechanics they healer can take care of it.

Examples when you call someone out for basically afk'ing / dropping things on the group:
  • "Healer adjust lol"
  • "Careful guys they may need to "carry" us."
  • "Who cares?"
  • "I can't believe you let me die."

Just because the healer can carry you through mechanics does not make it fun. Helping you basically cheese through content so you can half ass it / afk doesn't make you a good player just because you can get away with it. It makes you rude and regardless of how many Extremes / Savages (or lack there of) you have accomplished it means little if you can't even do casual content properly without harassing people who are trying to do it correctly.

It makes the game less fun for people actually going through the mechanics because they find it fun to do their best regardless of the content difficulty level.

Saying "healer adjust" to someone trying their best is not funny and ultimately it's just selfishness.
