Yoda seems eager to let major issues slide with Ezra that he is very critical of with Luke. I guess his metamorphisis into a crank is only about 65% complete by this point.
Yeah, but Ezra still has a master that will be training him, while Luke was irresponsible and went and got his killed in the previous movie. Yoda was probably just being lazy in Empire… when 900 years old you reach, eager to train young Jedi you will not be.
