It's fun to wonder, though, and I've settled on two wishes. The first would be making my beloved main into a Thunder Bluff NPC among the Druid trainers, kitted in full Tier 6 with an Origin of Nightmares. She would be friend and counselor to all young Druids and full of unsolicited advice for them, most of it incorrect. The second, less dignified, and perhaps more realistic legacy I would leave to the game is a series of cow-shaped impact craters at the bottom of various Northrend cliffs and in Crystalsong under the Dalaran sewers' exit pipe, in tribute to the several falling deaths incurred while mindlessly jumping from heights without the benefit of Cold Weather Flying. Little signs could be posted below informing players of the sites' historical significance, although I'm not sure how Blizzard could squeeze the phrase "Oh shiiiiiiiiiiiiiiiiii.........." onto the flavor text.
On the chance that Blizzard ever decides to honor your august self ingame, what would you want honored and how?
