I think that what also bothers me is that the love interest is also in the second tier, and although this was also the case in the first season, with recent episodes it seems like this has pushed every other character except Danny down the pecking order. Like we had occasional episodes or arcs dedicated to Betsy, Morgan, even the brothers upstairs (I've forgotten their names, and yes, one of them was the love interest at one point) all at the same time as dedicating time to Mindy's love life. Now, there doesn't seem to be any secondary plot. It's solely about Mindy, and there's nothing to offset her - I know it's her show, but there needs to be secondary characters with their own stories too. Which, like you say, is odd given that it's the second season and not the first.
