This did not work for me. I opened 1 pack of WOG when I was a new player before I even learned of those changes. When the pack rule patch went live I bought 10 packs of WOG and did not get a legendary within the first 10 packs of WOG. I currently have spent a total of 1100 gold for 11 WOG packs and have not gotten a legendary within those packs.
Just my 2 cents

Works great for me. Since the patch, I went back and bought some older pack to take advantage of the 10 packs opening. Got really lucky.
3rd Ungoro pack - Golden Sherazin, Tyrantus
2nd Gadgetzan pack - Golden Sergeant (Dust immediately) and Knuckles
5th Old Gods pack - Yogg
Basic pack - Opened a Alakir a while back from quest free pack.
