Will it get you more drops? Probably. But how long will those drops take to pay off the mats use use to make the top level armor?
If you like a certain skin and want to look that way, then I'd say it's definitely worth it. If you're doing it to get rich, I'm thinking it might not be. Of course eventually you'll get enough drops to make it worthwhile..but it's going to take a long, long time.
As I said, it's hard to say if it's worth it. It's a matter of perception. The problem is, no one really knows what they would have gotten as drops without the magic find. It's just not that easy. I personally use some magic find in the mix, without going crazy with it, or having a special set of armor. I seem to do okay. I also seem to do okay without any magic find and I seem to do okay with a lot of magic find.
I'm not sure anyone can guarantee it being worth it or not worth it. The only way to really test it is to do the same event over and over again for four or five hours, and the wait a day and do it again with magic find, and see if it makes a difference.
The thing is, how much of a difference it makes will have to be worth the price of crafting it. I'm not thinking it is.
