That said magic find isn’t fully drawn up yet, there’s not a complete pool of itemization where we can begin tweaking balance to a degree where we can ensure MF doesn’t get out of hand. It could turn out that we need to take an alternate approach, but, if I had to guess simply weighting the stat properly would be enough.
As Bashiok said, more types of item bonuses will be required to survive in D3. Mages won’t just be able to load up on MF and cruise through the game, as they can in D2. It won’t be possible to put every stat point into vitality, all types of resistances will (hopefully) be required, and more fundamentally, D3 spell-casters need +spell damage from mods to succeed at higher levels. Playing at Blizzcon earlier this year, my Wizard and Witch Doctor characters had achieved +100% Spell Damage from various items by level 15, and the improvement to my listed damage was obvious. Imagine how much of that modifier a level 90 Wizard will want? And if +Spell Damage and +Magic Find hardly ever occur on the same item, (as was the case with +%damage and +MF in D2) you’ve got a fairly neat fix to unbalanced MF right there.
You can read much more on this issue in the wiki.
Those facts established, what do you guys think about MF? Do you think Blizzard can balance it to be a cool bonus that doesn’t unbalance things, or greatly favor one play style or build? Did you like it in D2, and want it back in D3?
One thing Blizzard hasn’t yet publicly addressed is the issue of leeches. What’s to stop a player from loading up on MF and just tagging along? Since every character gets their own drops in D3, it will be possible to stay out of harms way while still getting items from every boss. Perhaps MF should only be factored into the drop for characters who are actively participate; dealing some minimum % of damage?
