For anyone who playes on private servers that have a +80 level cap, I have found an addon that is really helpful when it comes to leveling. BetterEXP is an addon that replaces your normal exp bar once you pass level 80. It also will give you average exp per kill as well as tell you how many kills till you gain another level. It's really helpful for 255 servers. It can be found easilly on Curse.com
