At least its not like the Factions expansion for the first Guild Wars, where you had at least three separate confirmation dialogues to go thru before you could start a mission. First was in actual dialogue, the second was making sure you were ready, then the third was just there so you could make sure everyone else in the party was ready. The latter two weren't even framed in the manner of actual dialogue, they were just your standard Yes/No prompts.
"Do you want to enter the mission?"
"Yes, I want to enter the mission."
"Are you SURE you're ready?"
"...That's why I said 'yes' the first time, dolt."
"Are you sure EVERYONE ELSE IS READY?!"
"I WILL PUNCH YOU IN THE SOUL."
