Yes easy, for most characters it is not difficult to combo into their Astrals, again, with some being able to do it off 5A. In that regard, looking at Noel, if she has a midscreen combo against an average life character around 35% HP with 100 heat and a burst off 5A, she can do a combo that will kill, but it has a chance to drop, why risk that when you could just do 5A > 6A > 6C > Astral? Granted I know Noel's like... the easiest character to Astral with, but'cha get my point, there are cases where Astrals are the most practical method of killing your opponent.
That sounds like a pretty demoralizing statement, something that'd easily fuck with your opponent's drive to fight.
