For me, it depends on the character and what his/her concept/back story is as to where I dump.
Even though I used to play Paladins all the time, and used INtelligence as the dump (as per 1ed), or clerics, and dumped into Dex or Int (for no real reason at all), my last two characters have been Bards... and I used Wis as the dump stat for the first one, and Str for the current one, because that is the way their concepts were written. (The current is an actor who "suppliments" his income from time to time. Int was needed to keep him from doing anything stupid, Wis to make him realize something was stupid, Dex for the Rogue skills, Charisma to get out of trouble when he does something stupid, and Con to make him survive doing something stupid.)
