Here is a Dwarf cheering after having just obtaining the World Explorer achievement. Note that he's not tricked out in epic purples or even blues. And no, this Dwarf didn't change clothes just for a photo-op. In fact, Tenen the Dwarf Warrior actually did most of his exploring in only his default skivvies. See, Tenen is only level 17. Tenen hasn't been fighting gnolls or completing quests, he's been exploring--and that's it.
My guildmate familiarly known as Nutty decided to complete the World Explorer achievement after discussing with a friend how much XP could be obtained simply by exploring. Nutty has quite a few alts, and wanted to try leveling one in a different way. World Explorer was the perfect goal to try for. Tenen explored Azeroth and the Outlands from March 12 to July 10, 2009. It took Tenen 4 full days of playtime to reach level 17 and complete the achievement. Being a Warrior was a helpful decision. It allowed him to "charge" into hard-to-reach areas. Summons (provided by me!) were necessary for a few final stops difficult, or even impossible, to reach without a flying mount and portals were necessary in reaching otherwise level restricted areas of the Outlands and Northrend.
Nutty is an RPer in Modan Co and on the Moon Guard server, and Tenen's personality made him the perfect vessel for this exploratory mission. Dwarves have a racial interest in expliration, and Tenen was the type of Dwarf who would be inclined to venture into dangerous teretories just to see what might possibly be there. Now the title proves it; that Dwarf has seen everything.
