[Highlander]

I don't really agree with the tinfoil arguements. I think Blizzard just like stats on items.

Item diversity that makes sense and is widely understood is good for the game, MF fits this bill. Unfortunately, just making up a new stat would almost certainly fail to achieve this goal as well (Eg: "+% chance to remove debuffs on kill" might not be so cool).

Also, no matter what happens, the RMAH is going to be hit with a lot of MF gear soon.

As for the options, I'm really torn. I MF gear swap, however I don't enjoy it. Sometimes I don't bother swapping back if I'm in a strong party.

CONTROVERSIAL OPINION - At this stage, I'm thinking:

Option 1: Capping your magic find
Not bad, depends on rate. If low I'd never bother swapping, but the that means it kills MF as a stat so not so great IMO.

Option 2: Magic find adjusts over time
2nd favourite - Pretty good, but I'd want a slow rate.

Option 3: Moving average of your magic find
No. Too complicated.

Option 4: Zero-out your magic for 3 minutes after swapping
My personal favourite, explaining why below.

Option 5: Gear swapping interacts with your Nephalem Valour
I like piss farting about with my gear, this would be annoying. Popups are annoying too. Please just don't.

At the end of the day, I think I'd like them to hardkill MF switching or something close to. Not so much because I enjoy it, but because it would help separate the highest level players.

If I'm skilled/geared well enough to farm in full MF gear all the time without losing serious killspeed, I want to be rewarded relative to my peers. I don't want my edge to be countered by a quick series of inventory right clicks.
