Please consider some adjustments to the restrictions listed in this thread: Realm Transfers and the AQ Event
I understand and agree with the purpose of the restrictions, just not the full scope. Specifically, you have created a situation wherein people who have paid to utilize one of your services are being retroactively penalized for doing so, as there are many of us who utilized the paid character transfer service to play with friends and/or family who may have wanted to go for the ultimate reward from the Scepter of the Shifting Sands questline, but are now unable to do so. For me in particular, my wife and I both transferred to play with some of my family. I had transferred previously and was still on cool down, so I waited about 30 days to transfer my main and leveled and alt instead. I transferred and have spent a lot of time on my main now gearing up and playing, and 3 weeks later found out that one of my lofty goals for classic would no longer be possible for me, all because I wanted to play with my brothers.
My suggestion on an alteration to these restrictions would be for them to apply to people who transferred after the announcement was made. If that is technically difficult, perhaps the transfer cool down could be adjusted temporarily to work around the restriction for people using this same criteria. Additionally, prevent any character that was created in this same time frame (from July 2nd onward) from opening the gates for 60 days or something of that sort. Otherwise, the restrictions will do very little, as people who will spend the money to transfer as a guild will just make the transfer anyway while having the people whom they want to get the mounts level a new character.
