I made a post back a bit about this and have finally tweaked it perfectly to my exp gear as well since im 97 now trying to get to 100. Here is gear needed and you can tweak what you want and ill explain reason to have it in your farming/lvling set.
1. Pickup radius, pickup radius and pickup radius. This is a crazy important stat not only for health globe realiant early builds but so you don't have to run anywhere near the gold pile to pick it up. I have 33 yards I find this to be enough. I wasn't happy at 26yards so I added another piece here its up to you but I highly recommend nothing below 20yards for speed.
2. Goldskin- Obviously the foundation for getting gold its not the 100% only for early players its the proc of gold droping per hit. If you have fast attacking hits. Nado/WW then gold is flying off the monsters and the gold that's proced is based on your GF%. This is why I still wear it at 97lvl as I don't need GF just need the proc.
3. Puzzle ring on follower- Ill be short and sweet on this one since there is a lot of confusion about it. I get 2-3 goblins per 15-20min run. 10 runs a day =20-30goblins. In a week that's 140-210 extra goblins. That's a lot of gold and 63lvl items, gems, tomes and stuff that is easily sellable. Not to mention best source of rings, ammys.
Now this basically covers gear. I also recommend having matching MF early on gear cause you want to find legends/sets and gear as well. I also recommend that your Pick up radius gear is not hindering you but top notch. View my profile I use IK gloves pickup and rest is 80resist well stated gear with pickup. You don't want to not be able to farm just cause you have MF/GF and pickup.
Pretty simple I tweaked it now to wear im using nado/ww for lvling because its well efficient. The Nado/WW hits a lot procing goldskin gold to drop and its great for farming no news here.
What is news is the fact I subout warcry. For threatening shout grim harvest. One of the best skills in game and highly overlooked. I use a method I call hearding basically gathering up mobs for a kill then cast it on large packs it has a short CD give 15 fury and gold and loot then drops off the mobs. Here is best part the shout is responsive to the amount of GF/MF you have so its better at high lvls. I have made a Ton more by using it. I don't slow down at all and get extra gold, loot sometimes legends, sets. Im still lvling fast but I have the right skills and pick up radius to keep it moving.
I avg about 250k per 15min run in gold picked up. Per hour you should be at 1mil. Sometimes ill change my run make it longer but in the end its same result.
As of today 1-28-13 218million gold picked up.
Earned achive- The One Percent on 11-17-12 which is 100mil picked up.
Hope someone finds this useful. Good luck in farming to all. Ill answer any question as I see them.
