One of the major differences from D2 - D3 is the commodity used for the economy (yes yes, this is obvious to everyone by now). This GREATLY impacts the economy, and results in a large impact to the gameplay. In D2 gold was useless, and D3 does a great job to make gold useful. However, it raises the question, is gold TOO valuable in this game? I would argue that it is. From my experience MFing isn't really worth the effort. From the many runs I have done I haven't really FOUND any items that are upgrades for me. This leads to a feeling that it would be more efficient to farm gold. Farming gold is like farming items, except it is really boring. In D2 I got this feeling that every time I killed meph / diablo / baal something AMAZING might drop. When I did meph runs i got this feeling of "OMFG this could be the run my HOZ / SS / Vampgaze drops." This resulted in a very addictive feeling of wanting to do 1 more run. In D3 I get the feeling that I'm playing for gold. Gold is what I want to get me any item in the game. Sure, it is much easier than the old D2 system. When I find an item I don't have to trade it for XXXX Sojs / HR's, and then trade those for the item i want. However, it is much more fun / addictive to hunt items. In D3 the best thing to do is farm gold, and this is very very very boring. This is a huge downfall to a game based on finding ITEMS. I find myself hopping on D3, doing a run or 2 which results in finding some **** rares or some rares I can sell on the AH. The end result is a marginal increase in my net worth in gold. Not too exciting, and the runs don't give the same feeling of excitement that at any pack kill something AWESOME will drop. ---------------------------ALSO----------------------- Bots in D3 compared to duping / bots in D2. Bots in D3 have a significantly increased detrimental effect on the economy. Farming gold is easy and efficient. Duping / bots in D2 didn't seem to harm me as severely. If anything, duping made HR's EASIER to obtain without actually decreasing the in game power of the HR. Duping made high powered and fun runewords more easy to create (since duping essentially decreased the currency value of HR's). In D3, botting is making gold less and less powerful, which is making it harder and harder to obtain items via the AH.
