The luck feat is kinda nice to have, and sometimes just worth spending the extra feat for it. I have a 'Luck Point' system incorporated into my campaign to prevent characters from dying as a result of a bad roll, but they only get one point per level. Once they are used, they don't get replenished the next day. Also the feat isn't too bad when you have several encounters in a day, and only one single roll can be changed out of perhaps 20-30 per encounter. And it doesn't guarentee success.
