Okay this excuse doesn't work and I'll tell you why.
Because you're the problem. An LFR wing would normally take 30 minutes (even with half-decent players) and you turn it into 3 hours. So where is your "life"? I argued that casuals have no life and pros have.
You would rather spend hours wiping on the same bosses each week and thousands of gold on repair bills than spend 30 minutes reading Elitist Jerks to learn your class. Nevermind the tactics, you can literally just stack with the tank on Garrosh in LFR and nuke everything down and ignore 90% of the mechanics
