Oh, you sure can smash people. Rage juggernauts have the hardest hitting single ability in the game right now. Much like marauders, they are extremely gear dependent. But, once you hit the gear threshold, you can knock off 1/3 of somebody's health in one attack. And it's an AOE attack, so you can lop off the top 3rd of half a teams health almost instantaneously. Ironically, the big problem with rage juggernauts is their defensive ability. They're kind of like warriors in season 9/10 of Cataclysm. Left alone, they will ruin anybody's day very very fast, but if you can force them into a defensive position they're much less threatening. If you can focus them while their defensive abilities are down, they're pretty much toast. Make no mistake, though. A well-geared, well-played rage juggernaut with a healer is the second most dangerous thing on the field behind a geared and healbotted annihilation marauder.
