99.9% of the time I absolutely loath them and would never ever use them myself, except for when it comes to fic for the game Chrono Cross where all of a sudden I run into this weird mental stutter. If you get to the game's developer room you'll run into one of the writers bragging about the script he made to make sure every character got their own unique voice.

And, dumbest thing in the world, every time I write something featuring one of the characters with a phonetic accent in game my mind goes 'That guy was so proud of those stupid accents! *guiltguiltguilt*' at me until I give in and write it out, even though I know how ridiculous I'm being.
