WP isn't really bugged like CM and AK was, meaning in WP you pull a ton of mobs and kill them all (for the most part). Killing stuff really fast isn't the same as skipping 75% of the instance. If you can speed through it on skill and not exploits its a really good thing.

For me it's great, not because it's fast but rather because I get to clear it on a timer. It's crazy fun to me to try and best my old times... Not so much fun just drifting through it the slow way.
