So your warlock does his thing and hides. Depending on the enemies' initiative order, the dragonshields either blindly attack likely squares, or the wyrmpriest goes first and points out where you are. At that point, I presume the dragonshields can see you and attack you normally, correct?
There is no reason to believe that they can see you at that point, as you still have concealment and are still using it to hide. They can attack where the wyrmpriest is pointing, although it's quite a trick to point out a specific space; in that case, they take a -5 penalty to hit you assuming they swing at the right square. Of course, a fey pact warlock is likely to be teleporting all over the place, so they might not still be targeting the right space by the time their attacks come up.
It's not a flawless defense by a long shot; enemies can still blanket the area with fireballs or whatnot. It is, however, a very nice defense, especially if you crank up your Stealth check.
This also raises (for me at least) the question of whether a creature that's been Warlock's Cursed knows it's been cursed. It's quite feasible (in theory, at least) for the Ninja Warlock to skulk around the battlefield unseen before his buddies show up and get everyone cursed up in preparation. The disadvantage, of course, being that if you do get spotted you're out there alone...
