Both Wild Strikes and Raging Blow are procs. That is where the trick really lies, in aligning 2 procs of RB (Berserker Rage can be used to create on in case you don't have the two) and then you weave HS into CS as a Rage Dump. Now the rotation changed a bit with the Galakras trinket and Storm Bolt, having to get that into CS too every 2nd CS. Wild Strikes is what you do outside CS while waiting for BT to come off cooldown.
I tend to agree with you that it's not that proc-ish, but the procs do influence the rotation a lot, but in a different way then with Frost DK for example. With Fury your procs essentially decide how your rotation will look like for the next 14 or 20 seconds. And every cycle the rotation can change.
