I think it was the fact that they had to combine season 2 and the original season 3 in order to pull off Beast hunters. Thus the season was left with one shot episodes mainly. This resulted in some underwhelming moments here and there. I personally wasn't a fan of the concept of the relic hunts, despite that I did find Triage highly enjoyable though. The season wasn't the best but the finale was pretty much its best episode in my eyes. I am really excited for Beast Hunters. And I'm pretty sure there wont be any Cybertron in the next season given that it is dead.
