It didn't involve an enhance, but to be fair the blizzcon grandfinals where Jungyup, Sleepings, and Goochi won as PHD was one of the most exciting blizzcon finals ever. People in attendance were throwing things and screaming at points, and both the wow and AJ forums practically exploded. Most of the other blizzcons you can barely even tell a crowd exists, you can mostly just hear people rustling snack bags in the crowd and 1, maybe 2, threads pop up about it.
This was due to crazy/risky ballzy play by the pally, which carried that comp. I remember people trolling the hunter for backpedaling during games sparking "is backpedaling bad or just repositioning" debates. The enjoyment out of that comp was watching a healer play out of his ass to carry a sub par comp.
