No, They've screwed up their Fan Ideas of Mandalorians. Unless you are the Creator, or have Clearance FROM the Creator of something like SW, Trek, or B5, like it or not, all the stuff you can Imagine is NOT canon unless Approved. IE, the Reliant was a MIRANDA class Vessel, not an AVENGER class, and the Enterprise Refit was STILL a Constitution class Vessel, not an Enterprise Class Vessel. Now George has Generously made some things like Pink 5 Canon, but once again, it's his discretion.
I Don't see how he "Messed up" the Mandalorians. It was stated that they and the Jedi have been Opponents for Millennia, and only now are they out of favor as a faction, WHICH is faithful to the Cycles that the Republic seems to go through, and can be seen in our own history.
