The server issues worldwide are still causing havoc for people trying for this, but I have a relatively simple idea, and I have tested the premise by taking one hour and trying (repeatedly) to access the servers and deliberately trying to dl my friends' things. There is a way to access the servers quickly and easily and if you tell 5 friends, you can get the problem chiev (I'm at a mere 1 dl atm myself, but hey-ho) for 5 dl's of a single piece of content. the steps are simple to get into the dl server and to your friend's things.
1) go into online, then community creations. When you reach the download choice (may take a few tries) select it then immediately press x
2)now, set search parameters to friend content. go down to search, and start it up again.
3) count out 10 seconds. if it doesn't load in within that time frame, repeat the pressing of x and step 2. If you wait much longer, the server may crash, and it should load within that time-frame. By re-searching, you stay in the server network, and when it comes back up, you will be near the front of the line.
I also highly recommend trying this at different, low-traffic times of day, though I tested the premise from 6pm til 7pm central time and was able to download 7 friends' content items in that time-frame.
It's tedious, but with this procedure, one could conceivably set up a boosting session, friend 5 other ta gamers for about an hour, and all 5 of you go to town until everybody gets the pop.
Good luck and happy hunting!
EDIT if you would like me to try to dl your content item, please send me a friend request on xbl with the header "WWE 12 DL" and I'll add you, and include you in my multi-time per day searches. I only ask that you return the favor and dl something of mine in return.
EDIT #2: I a no longer in possession of thisgame at press time, so I regretfully cannot do the downloading thing at present. Will hopefully have it back within the month, so will keep you all posted.
