Indust when he cares is probably still a better medic than Nursey, but without knowing anything whatsoever about the situation it was pretty obviously for non-skill related reasons, indust has had a tendency to vanish for long stretches of time the past few seasons and he generally gives off the vibe of someone who feels burdened by having to play for a non top 2 team every time he does.
That being said, I think people disliking Indust has made them rate him much lower than his actual abilities, I would still have him as a top 3 medic at least if not higher.
