Changing firing modes so quickly is making Mandalorian as a class extremely versatile. If Jedi misses his Force Speed Lunge attack Mando can take his time change firing mode, do a 360 degrees spin and hit the Jedi in the head as you are stuck in repeating itself bugged animation that won't let you to move. Mandalorians get a little too much time for that. It certainly should be possible but require something more to pull off. Changing firing modes should have a more meaning and follow a consequence.
