i talked to some of my CMD yeah.
I get your point, but honestly, healing someone right now takes like a 1 minute + minimum if they got max health points. Add to that the lack of medics sometimes and the number of troopers getting shot and the medics end up just sitting doing nothing but holding their LMB from one person to an other, i think adding the bacta grenade (and im talking like 1 or 2 for each medic) would add some tactics and situation reading for the medics. They would have to use the asset at the right time and the right place. My experience as a medic has been pretty dull over all, i just think that could spice it up.
Also, i dont consider naval to be combat medics, mostly cause they dont got armor and are more of a rp role.
