Looking through the forums to make an educated decision, I've not only realized that what I want to do with my accounts is not able to be done, and many other players are in the same boat as I am.
While I understand the need for certain migration restrictions in order to prevent the abuse that would follow from an unrestricted system, what we have now is TOO restricted. This was a good step to make in bringing Cross Save to Warframe, but for those of us that jumped on the first account migration did so not knowing there would be a much better opportunity down the road. Those of us that migrated accounts years ago are now being forced to make a very tough decision on making sacrifices to link/merge accounts.
I myself simply want to merge my Xbox account to my PC account, and keep everything from both. But since I migrated my PC account to my Switch years ago, I'm unable to do that. I could just go ahead and link all of my accounts to my PC account, but I would be losing an unacceptable amount of money doing so.
So in speaking for myself and other players with the same situation I have, it should be logical that if we want to merge an unaffected account (my case the xbox) with our PC account, it should be allowed since we paid for what we paid for. I do NOT want to be able to merge a migrated account (in my case the switch) back in to the main account for obvious reasons. I am completely comfortable overwriting my Switch account with the PC account, but not another account I essentially built up from scratch.
A solution I would like to pitch: One account will permanently be set as the primary account, and each platform will have one merge slot that will be a one time set.
Example being (for accounts that never migrated): I choose my PC account to hold primary status, and I can merge 1 account from each platform. So everything I have on the Switch, the Xbox, and Playstation will not be lost. With every platform account now locked into the link, they cannot be changed. If anyone ends up having account issues, technical support could provide functional solutions and a potential reconnect depending on the situation.
An Example for accounts that have migrated in the past: I choose my PC account to hold primary status and will merge 2 unaffected accounts (Xbox and Playstation), but will have to overwrite the Switch account to link since that one was the account that was migrated. Rules will follow the same as the previous example.
The goal here is to allow previously migrated accounts to still merge unaffected accounts ONCE so there is no money wasted and to still prevent as much abuse as possible.
