Spoiler:
M1 absorb is a bad-bait outside of roaming ~ compare it to the no-CD Pounce iteration from Live (i.e.: 24/7 AP-starved, bad and pouncy pointy-ears); if you pop/run the M1 absorb you are pugging, solo roaming or forgot to swap morales in 9/10 cases... as quite literally all morales - but maybe the shite dps ones - are more valuable especially M2 (in conjunction with morale pump).
So meh.
