Old Matticus on the left, new (old-er) Matticus on the right!
I can easily explain the hair and color change. The buzzcut is a result of dodging Fireballs and various Shadowbolts. The color is from the age and stress that comes from the weary campaigns against Kael, Vashj, and IllidanÃ¢â‚¬â„¢s forces. Mallet is older. Much older. The new look helps reflect that. The beard is longer from the lack of contact with civilization. HasnÃ¢â‚¬â„¢t had time to properly get a beard cut (trim).
What about you? LetÃ¢â‚¬â„¢s see your haircuts!
