The mechanics and requirements of character progression has changed a lot over the expansions. So what do you sort of miss now, that you hated at the time?
For me it is weapon leveling. Althought I hated it at the time, it brought a sense of reality to a character to have them train in different weapons in order to be able to use them, not to mention grinding out 300 points in unarmed skill by slap fighting a buttload of pirates.
So what do you sort of miss now that isn't in the game anymore, that was a huge PITA at the time?
