[quote]After waiting the 90 days, I STILL was unable to unlink the steam account in which I do not have access to. Is there ANY possible way for me to disable my old roommates steam account that's tied to my profile so I'd be able to link my personal steam account?[/quote] No, the March 25th change that you mentioned permanently removed the ability to unlink accounts (except Twitch) from Bungie profiles and Bungie are not giving any exceptions to the change. Bungie expected people to unlink the accounts within the ~6-7 week period prior to it after they issued the announcements. [quote]Side note, this also screwed me over from playing the Marathon closed playtest because the game wouldn't recognize my steam account after redeeming the playtest code.[/quote] That's intentional and likely to prevent people giving away their code, so there are other checks that happen once you've launched the game to make sure you're actually allowed to be in the playtest with the account you're using. The code itself is just for the download.
