At first, all my toons were various spellings of “Kaercha”. My friends complained that it was too confusing, so now they are all Kae + hero syllable. Mane is a reference to Whitemane, my favorite DK. Kaezhul is a reference to Nurzul, my favorite shaman. Etc etc.
Some of them get silly. Kaedgar sounds like Canadian Kadgar. Kaegall sounds like a pelvic floor exercise, etc. but it’s fun. People who play a ton of toons are generally not as good as someone who mains a single class at that class, but they have breadth instead of depth.
