I have not performed any linking or merging yet on any account, but I am wondering if unlinking accounts will be possible- When I first started playing warframe it was on XB1 with my dad's account. I got to mr9 and have a decent amount of stuff on that account that i would like to have access to, but i do not want my dads account to be permanently attached to my warframe account. Will there be a way to unlink accounts after performing a merge? Or am I S.O.L?
