Say a party is going up against a dragon that's their CR, or at least close. The dragon dives in and picks a character up, say the party cleric, using the snatch feat. Now, instead of dropping the character, the dragon flies away with him/her, gets a good distance away from the rest of the party, then simply kills that character. The character would have no chance in a one-on-one battle with the dragon, and probably wouldn't even be able to hurt the dragon very much before they were finished off.
Then, the dragon flies back to the party and picks someone else up, flies off with them, and kills them. And repeats the tactic until the entire party is dead.
Is there any reason this tactic wouldn't work? It seems to me that the snatch feat is a very easy way for a dragon to split up a party, since it's almost impossible to break a dragon's grapple. And there's no reason a dragon wouldn't use such a brutally effective tactic.
How could a group possibly avoid a TPK when fighting a dragon?
