Wow this thread was totally not what I expected. I thought you were going to ask a question about what a Calling is...
now, if I understand what you are asking. Which calling is a good melee dps class.
So you have Melee DPS Clerics, Melee DPS Rogues, Melee DPS Warriors.
Rogues can Stealth, Warriors have lots of gap closing abilities (charges/thread the trees/etc), and Clerics are just ... hai in ur facez! annoying, cause they don't die (heals). But ya...
Overall, it comes down to a preference in playstyle. Do you want to be sneaky? Rogue. Do you want to be all up in their faces ripping them to shreds? Warrior. Do you want to be able to do 'ok dps' but be able to heal yourself? Cleric.
Most classes are Warrior or Rogue. The Clerics I have seen so far are usually either healers or caster dps. The melee clerics tend to go out solo'ing rifts, but not too many floating around in the warfronts yet.
