Tying MF into paragon levels hugely discourages playing alts, and alts give the game replayability and a lot of interesting options.
I simply don't understand why they did it. Yes, I read their explanation - it's just that it was like reading Charles Manson describing why he had to kill people, it didn't make any sense.
If you want to do more damage, you look for more primary stat, crit, etc. If you want to survive better you look for vit, AR, etc. If you want to find more gear, you look for MF. Except apparently that last one was too difficult for people to grasp.
Yeah, I know I could suit up my 60 DH and 60+18 barb with some MF, but it's not the same. The gear doesn't feel "permanent". They're currently naked, as I see no reason to play alts given the changes Blizz made. Selling their gear has allowed me to better equip my WD for the paragon grind to get back to the MF I was at before the patch since, having a brain, I decided to get MF gear since I wanted to MF...
This idiotic change which wasn't thought out at all has really dulled the game for me.
And yes, I'm still a bit sore that my expensive MF suit became garbage with 1.04, it's taken me this long just to have more than a couple million gold again since I sunk everything into my new WD main (was waiting for 1.04 to hit to make him my main, with the pet buff).
Don't get me wrong, I think 1.04 is a quality patch. I think paragon levels are an excellent idea. I'm just not OK with the idea of tying MF into them for the reasons stated.
