User blog comment:JakePT/Deception Out, Response Abysmal/@comment-1691295-20120131024125/@comment-1691295-20120131035155

Going through the list, there's actually very few issues that affect the canon outside the internal events of Deception. Quite a few are just things fans don't like because they weren't previously mentioned (Gas-suckers/Asari Kiss), and there's quite a few that are just bad descriptions that don't affect canon at all.

The most serious problems are the Batarian Embassy, Aria's knowledge of Cerberus' involvement in her daughter's death, Anderson being with the Council, Gillian's Age, Gillian's condition and Aria's family. Beyond that they're pretty easy to handle.
