Other perks include good drop rates of Frostweave and cata greens for DE. Both which bring a decent price on the AH. Rep for the various achievements. Patterns / recipes for the OCD who must posses all patterns.
And best of all is the speed for which this can be accomplished. A averaged geared alt at 85 can one or two shot most mobs. Good AOE can bring down a slew of mobs for looting.
In conclusion, if you've become bored with the rut on TB / Molten Front. Think about Northrend. I enjoy it.
