Several nights a week I partake in inferno magic find runs with a friend or two. We joke and have fun, possibly find some decent and occasionally excellent items, and enjoy the quest for loot.
My favorite portion of the diablo experience is to hunt loot, and the challenges of finding and fighting the packs of monsters is a relatively fun way to achieve items (especially with a partner or two). Comparing this new method to Diablo 2's boss runs and clearing monster level 87 areas, I think the NV system is a fun way to go about magic finding and results in longer runs and less new game creation.
That being said, the question arises once more of whether or not people feel satisfied from the reward of doing such a run. In Diablo 2, if you found a low level item with excellent affixes you could upgrade it to the next tier in the horadric cube. This gave low level items potential value, thus a little excitement in finding them.
Diablo 3 leaves low level items in the dirt, with affixes not even being able to reach their maximum values without them being spawned on a level 63 item.
The argument of whether or not these affixes are as exciting as those in Diablo 3 is real and has some substance, but the chances of those being adjusted are slim. BUT, if more items could potentially spawn maximum value affixes then perhaps the sense of reward and even the value of a <ilvl63 item will perk up the magic finding experience. For instance, if a level 60 armor could have a reduced chance, but at least SOME chance, to spawn 80 all resistances. The armor would still be lower leaving it less valuable than an archon armor with the same affixes, but at least it has a chance to be respectable gear. And yea, uniques suck as is with only a handful of exceptions.
I have a lot of fun with this game, and I only see room for improvement rather than a problem needing to be fixed. I know that Diablo games are not so quick to give a player a ridiculously good item. It takes time, luck, and more time.
I'm hoping to hear from more people who are still having a good time, and maybe some magic find stories, comments, or ideas for improvement.
