Ah, don't listen to them.
Ideally I'd love to have it like Rift, where I can have as many specs as I want provided I'm willing to pay the amazing fees for them. Given my options I'd probably do the following on a Consular/Inquisitor.
Melee DPS
Ranged DPS
Heals
Tank.
Rogues are great for soloing, ranged is imo, easiest in group, especially if there's a lot of mobs or highly mobile combat, and I've always enjoyed healing.
