I'm still confused on why this clear abuse of something not intended to be done was not fixed. Is Bioware not able to figure out what they are doing? I've seen a few of these assassin/sage bots right when they were created at 65. They enter the gravestone in some chapter and never leave it. They go the whole way up to lvl 70 without ever leaving. Which means whatever they are doing rewards XP. Which also means they are either killing mobs or completing a quest/the chapter. The question then becomes, how can they endlessly complete a bonus quest or kill mobs when you have to leave to reset it? Clearly they are exploiting something to reset it or found a way to make a mob respawn endlessly to kill.
There is a big difference though between bots just farming regular crap vs exploiting to gain credits at a possibly very high rate.
