Just becareful. If you in your logic are losing gold when farming some paragon xp instead of spending the time on ah. Your losing money right now not being at work. Its a dangerous way of looking at things. Everything will be dull quiet quick... Maybe your just to old for games, since you look for a higher meaning while playing a computer game.
Wouldn't getting to paragon level 100 "accomplish something". Some people set different goals, some financial - such as 100M gold (or 1M gold). Some to beat Inferno with all five classes, maybe get all achievements, hardcore, now there will be monster power and creating that hellwhatever ring. Really there are a lot of things to "accomplish" in the game if you so desire. But if you aren't having fun in the game, don't play or take a break. Maybe some time off will let you enjoy it again in a few weeks/month(s).
Not sure why so many are dissing you. It's definitely a quick way to make money in AH, but it's not always ez as there are many flippers/snipers.
well not only that but there are some bots that are so freaking fast ;( but still u can make few mils per day no problem (from 5 to 50 mils even more )
