Transcender for 70-410 prep

For those that have used Transcender, perhaps you can understand my frustration.
Is it just me or is there way too much focus on Server 2008 in these questions? I'm running through WGU 70-410 course materials and Transcender is part of it. Most of these questions reference a lot of knowledge with Server 2008. This includes knowing about introduced and deprecated features of Server 2008.
Am I to assume that I can see a lot of Server 2008 material on the exam? I just had an ISATAP question that straight references 2008, not 2012 R2.

Also don't forget that there are a lot of features that didn't change a whole lot between 2008 and 2012.
