mythic dungeons are carriable

Being carried and time wasting aren't the same. Time wasting is when you are assigned to a specific duty and fail repeatedly, while showing no signs of improving. This is time wasting. You can always swap to an easier role or leave. If you refuse to swap to an easier role or leave, you are a douchebag. You are saying your experience of trying for the 4th time is more important than 4-29 other peoples time. This is attitude, and its basically the only reason I kick people.

mythic dungeons, as well as every other aspect of this game are carriable, like it or not. There will always be someone being carried. When you realize this fact, you'll learn to just suck it up and move on.
