Seems a tad generic, but given the MC is a healer I'll keep an eye on it for now. Healer being my favorite role on games / MMO's, I'm mad that they always get shafted in these Isekai stories, lol. Some really shitty gods must govern all these worlds if they're idea of balance completely excludes the support roles.
It honestly sucks, man. Most of the time the healer role in manga is completely turned upside down, be it by some dumbass pumping all his bonus stats into evasion, or having his heal be a plot mcguffin that literally does anything and everything he wants. And, on the rare occasion that we do get a good representation of a healer, the manga either gets cut short(Life Howling), or has some fucking god awful side characters / drama. (Live Dungeon)
