This was for me the weakest episode so far, I still enjoyed it, but I feel it could've been improved in a few ways:
A) Make it clear that the random blue guy is being dragged along for a good reason, maybe he has experience of Imperial Tech (which is sort of implied, but stating it up front would help), that would give a good reason for him being there
B) Somehow make it clear that the majority of guards at the base are rookies or the dregs, I'm guessing a stretched empire would have to make up numbers
C) When disabling the safety seals have them roll a success with a complication "hey guys the seals are deactivated, but i I errr somehow tripped the bases security" explains them having to shot their way out as well as gives the blue guy more of the bumbling oaf development
D) Make it so not all the troops are hellbent on killing/capturing Mando & crew, they are there to protect the base, show them desperately trying to re-engage the seals
e) have the lava flow wipe out a couple of the low flying ties as the heroes just make it out in time only to be confronted by the final Tie which Razor crest deals with
Not big changes but I feel it would have given the episode better flow
