I removed subject A from wow for a week and monitored his activity. (This is not meant to insult wow players. It's just a joke about those who actually freak out on maintainance day.
Subject did not do much. Occasional boredom, irritation. They mostly sat about, occasionally asking about wow. Not much activity.
Subject's pulse had quickened along with heart rate and increased blood pressure. Subject began wondering about raiding stats, Gruul's hit points and Archimonde's tactics. Mostly raiding and PVP were talked about at dinner. Subject remained healthy.
Subject attempted to log out of real life and suddenly became interested in lore, particularly Archimonde, Naga and Illidan. Also noticed change in accent, particularly Scottish accent became prevalent. Subject also woke up in the night, speaking Eredun and crawled onto the ceiling, again speaking Eredun.
