My memory of ravager is that it was used to achie ~5.5k dps in some vid to clear SM cathedral in 1 pull by a level 38 warrior, was lvl 60s pulling an healing though. Fun to watch and did make me think, surely this has a use in raid enviroments, but sadly now the best I can think of is the phase 3 neth zerg, but really any place its ok-ish involves very weak mobs to AoE anyway, but still reasonable dps output on cloth, so the best thing a prot warrior can do is slow and taunt things off still.
Another weapon I've seen is the
[Manual Crowd Pummeler], at 500 haste rating for 30 seconds I wonder if it would be worth using as a near 0 (well 29) 2H dps weapon, but with the on use haste bonus could still out dps a top end current epic until its over then swap in the usual weapons, this thought could apply to any arms warrior potentially. The major problem though is that the use has just 3 charges, so you would have farm the crowd pummeler boss in gnomeregan quite a lot to actually have enough to do anything, ultimately making this nothing more than a gimic even if the dps it does is good.
I also remeber there being 1% chance for an extra hit trinkets in game, though never in the slightest bit really looked at them and know whats happened to them since, but those were very popular at 60 with rogues and warriors.
