Ok I think I got it. If 2 melees are in a standard flanking position (opposite sides of the enemy) any ranged attack from anywhere - no matter where I am - will grant me CA.
Not quite as good as I thought - I think my DM knew I was a noob and let me have it my way the first time around.
Yeah, it's good, but only if you have the right party for it. If the rest of your party is melee-heavy, and tactical enough that they often try to flank opponents, it'll work well for you - but if not, you may be better off looking elsewhere for achieving combat advantage.
