It seems to be taken as a given most places, but I find it highly unlikely that Warrior is putting in so much more work than the other tanks. If you look at FF logs for Susano/Lakshmi runs, Warrior is well ahead of the other tanks in every percentile except >90% for Lakshmi and >80% for Susano. If the bottom 80% skill Warriors out-DPS other tanks in the same skill bracket, I really doubt they are working so much harder than them to get that lead. Let's not pretend that Warriors are chosen only by professionals. At the end of the day, you're just pressing your buttons in a certain order like everyone else. You shouldn't be making balance decisions based on how tough you think your class is to play. Those logs are also mostly pre-4.05 logs, so it would be even more skewed towards Warrior if we started over.
