You gave us a Glyph of Corpse Explosion. You told us it was for fun. How fun, really, do you think it is to explode 1 non-boss monster every 15 seconds?
Death Knights feed on suffering and thrive on despair. Why not let us represent that with the gory destruction of any corpse, anywhere, anytime?:
-You're in Warsong Gulch and a rogue jumps you. After 5 minutes (because you're blood) he's dead at your feet. SPLATTER. The stealthed feral who watched all but did nothing reconsiders his eventual yet messy demise and goes back to camping mid.
-Your guildmate never learned not to use auto-run and afk. Teach him and the rest of your raid a lesson after Garalon kills him. BOOM. I'm sorry, did you want to be rezzed? Maybe you should have been more careful.
I remember a Warcraft of meat wagons flinging filth, of acolytes eager to stab themselves just to serve as my eyes. Return to our messy, violent roots. Give us mastery over death, instead of mere Gin-Ji Knives. Change this glyph.
