Truthfully, I think it could have been useful to develop Crusher's staff more. I mean all we ever saw were Ogawa & Martinez. Seeing to the medical needs of a population of 1000 would require a developed staff, & the existence of Selar's character in season 2 suggested such a staff. If not to keep her around, then they should have at least added another medical staffer or two, with speaking parts
Hell, they could have scrapped 2 or 3 of those awful Crusher episodes like Sub Rosa, & put in something medical staff oriented, which would have still featured her heavily. I would have found a few more Starfleet medical stories fascinating
Geordi & Data had numerous episodes centered around technobabbly problems. A few centered around medical sci-fi would have been very refreshing
