This shift could signal a few things. Given Schlerf's short tenure (his Linkedin profile says he left BioWare last September after joining in November 2013), he may have been a contracted employee, with his duties ending once a bulk of the work as lead writer was done on Andromeda. That'd make his leaving a normal course of business.

The other possibility, when combined with the rest of BioWare's high-level exits these past few years, might be an indication that something is afoot at the studio and leadership-role workers are leaving for better opportunities sooner rather than later. We've reached out for more information and will update this post if anything becomes clearer.

To confirm what some folks asked about a few months back, I am no longer working on ME:A at BioWare Montreal. — schlerf (@schlerf) February 16, 2016
