If you're a COR who doesn't deal damage, you've failed at the job class.
I really don't understand why most of the posters on this site shout this in every thread they can.
I don't think most of the posters here DO really say that. What they really say is that you should be doing SOMETHING besides just standing there and rolling. If you're only rolling and standing around, you completely suck. Plain and simple. Is it possible to get invites from desperate people with low standards (or high desire to get e-peen WS numbers)? Yes. But you damn well better be doing SOMETHING productive in addition to your rolls.
Main ways people do that:
1. /RNG (or /WAR) and DDing. A lot of people like this and it's a very obvious choice, because COR has access to quite a bit of gear that is well suited for adding damage. You should at the very least be prepared to do so, in the event your party has a puller already (so COR/NIN is less useful) and doesn't need a lot of extra support (COR/DNC is less useful if you already have a lot of support - say, a DNC or /DNC in party, or multiple mages - you'd be better off adding damage instead of even more support).
Note that DD becomes much more about gaining TP for WS at later levels, but you will indeed be spending a lot of time shooting your gun in the mid levels. Once you get a multi-hit weapon (M.Kris or Joyeuse), ammo costs decrease because melee is much more efficient than ranged DD. Some of the higher level single hit daggers are reasonable options too, stuff like Jambiya and Behemoth Knife. A COR who pays attention to WS and rolls and uses a single hit weapon is a hell of a lot better than one who rolls and stands around. You really need to be shooting for TP from 22 to AT LEAST Slug Shot level (54? Can't remember off the top of my head) though. Your WS are simply too weak, and you'll get pretty good damage from /RA to add to your party far more than... just standing there and rolling. And you should at least have a solid ranged set for situations where you might want to be at a distance, as it comes up a lot for any COR no matter what your preference is.
2. /NIN and pulling. I actually kinda enjoy pulling sometimes, and though some here hate it, COR is at least capable of doing it (very well at merit camps, not as well prior to that but still certainly CAPABLE). Note that this still requires gil. You're still gonna be using consumables to pull, and at pre-merit levels you have plenty of time to pop off a couple /ra during the fight too. You're also going to be spending gil on ninja tools. Hell, I even have some nice evasion pieces to go along with my capped evasion skill for when I pull.
3. /DNC and becoming an uber-support character. Box/Quick Step, Drain Sambas, emergency spot healing with cures. Add that to a little DD and the rolls, and you're doing a ton for your party. Potentially the cheapest way to go too, as you'll want to be in melee range to keep up sambas and use steps. A good low delay dagger or a multihit weapon (M.Kris or Joyeuse) are useful.
4. Japanese would say /WHM and backup healing is a good option, though it's generally not accepted by the english-speaking COR community outside of lazy people who just want an excuse to stand on the backline and occasionally throw out a cure. Even if you do think that's a good idea (I don't, but for the sake of argument let's say you truly wanted to play the COR/WHM role and not be a gimp), you'll need to invest in some MP and mage-type gear.
5. Focus on adding as much Quick Draw damage as possible with /RDM or /BLM. Very specific situations though, generally for endgame HNM type mobs that are weak to magic damage, and your ranged or melee attacks aren't as useful.
People whining about "it's expensive" are also annoying. By complaining about costs, you're pretty much admitting that you think the stuff that costs money is useful. Otherwise, why complain? If you don't like the idea of needing to earn gil, and you're just interested in buffing people and supporting without adding DD, BRD is a much more affordable option that might be a better fit for you.
