I agree with everything you said logan. I get the distinctions between the Consulars and Knights as they are intended in TOR. I just think they shouldn't call them "Knights" - they should be called "Guardians" like they were in KotOR. The reason is because both Consulars and Guardians are Knights (as are Sentinels) in the traditional sense of the term (a graduated Padawan).
For example, Obi-Wan is the archetypal example of a Consular, which makes sense to me, and Mace Windu is the archetypal example of a Guardian. They are both Jedi Knights, however.
Like I said in my OP, it's not a big deal and I don't really care, I just think it was a poor decision to change the name since really all graduated Padawans are Jedi Knights.
