Personally I think this log already exists so there isn't much time required to dedicated developing. At most it needs a parser/filter so that it can be accessed by players flagged as GL. I'll break it down to three sub-questions:
- Would this feature be useful? Yes
- Is it necessary? No
- Should devs spend their limited time fixing/adding something else? Yes
All alterior motives aside, I could be RPing a thief.
[edit]Voting with an alt account, seriously?
People here answered "yes" to the "necessity" question bringing up a lot of situations when such a log would be necessary.
