The fun in most arpg for me is to obliterate enemies not grinding.
Without using shortcuts grinding is unfortunately the only way to gear up to be able to quickly obliterate enemies. If you add to this that we have a random item drop system even for crafting you have to trust in luck or use a shortcut. Okay shortcuts are trading with or without AH/RMAH. Not okay shortcuts are bots and illegal shortcuts are hacking/exploiting.
Grinding and trying to just run through content as fast as possible over and over again is not something i call fun its something i call repetitive necessary evil and in most other parts of my life repetitive tasks are something i try to automate so i can instead use the time for more worthwhile endeavors.
If everyone that used bots had no impact on the rest i wouldn't care about bots but since they just as often have a negative effect on someone else i have come to dislike them and that's also what keeps me from using one myself.
So i will probably either stop before getting more than halfway to pl100 or sacrifice my satisfaction in getting there by either using a okay shortcut or becoming a human bot and try to maximize grinding speed.
