didn't see anyone post this yet... but i just re-read the blue post about 107...

MP 10: 510% (up from 160%)

uh... i think i'll start "farming" mp10 now

yes it will be slower, but at almost 5x the exp, i think its worth it? maybe skip the elites, and go for the trash mobs only?

Don't forget about the NV stacks. MP9 with 5 stacks would be +495% XP which is pretty much the same as 0-stack MP10.

If you're not worried about dying, then your kill speed is almost exclusively about monster HP which scales +40% per MP level from MP3 up to MP10. The relative XP bonus, however, scales:
~20% XP per MP level excluding NV and Hellfire Rings
~17% XP with Hellfire rings on you and follower
~13% XP with Hellfire rings and 5 stacks NV

Going MP9 to MP10, you're facing +40% monster HP for a relative 13-20% increase in XP (and the MF/GF, bonus item bonuses, ofc).

Blizzard is throwing people a bone for playing on higher MP levels. If you're only XP farming, the same rule of thumb still pretty much applies - play the highest MP level in which your kill rate doesn't decrease. What's nice about the change now is that if you decide to play MP4 to farm keys, for instance, you're not getting screwed out of as much XP/hour. I really like the balance they've struck with the new numbers. We'll see if they stick.

The only potential issue is that if the proposed numbers are implemented, HF rings lose a lot of luster.

Small price to pay overall, I guess, but that would be unfortunate.

The biggest thing this helps is Wizards. There's tons of videos out there of pretty much every other class doing 100 million experience an hour, but the wizard is stuck straggling behind them doing 60 million an hour. While other classes will still be ahead of the wizard by a lot, it'll still bring the wizard at least closer to the 100 million mark. I usually play on MP3, but can probably do MP4 just fine now so I'm very excited to have the 75% more experience.

I'm XP farming my WD on mp0 at the mo

Might have to move to MP1 just cause the XP increase is worth it.

Yeah this was the huge thing I noticed. I'll be tanking MP10 with the wizard, who cares if I die a little with this kinda XP LOL

i dont know how high of an mp i can archon farm, but i know its not mp10
i'll have to do some testing with archon on lower mp, and cm on higher mp... lets see where the happy medium is

I'd love to be able to do MP10 for exp but until I can get a better weapon and a hellfire ring to swap with my Leoric's Signet the highest I can do with any level of efficiency is MP2.

add me ^_^ we can farm together : D 7 lvl to 100

Is the number just applicable to Inferno?

If it is applied to Normal through to Hell, I can see that leveling to 60 would be so much faster, especially with high level helping.

It should be applicable on all difficulties. I'm currently doing MP10 nightmare with my level 48 barbarian and I'll get 2 levels just in the Arreat Crater, full cains set.
