[Opinions] Not senseless! Makes perfect sense!
Especially if you think of the last syllable as -eh and not -uh.
Raphael pronounces the -el. Israel. Azrael. AE is not uncommonly pronounced as two separate syllables. Michael puzzles me a lot actually, none of the other archangels clip their "el" syllable like that, it should be mick-hie-el IMO
