It's actually even a little worse than that. Because JP items currently match the heroic tier (as opposed to being spent on higher tiers as we progress) and because there is no out expenditure for the points (think gems, or honor, or rep), you bloat on JP and gear quickly, making already tedious heroic runs even less appealing.
But that will change as the patches progress, in theory.
Hell, last night I took my 80 priest herbing in Vash, did some ramparts runs with my 62 pally healer, and healed heroic HoO with my shammy. By far, the least fun was had on my shammy, which saddened me a little bit.
