I can only say good things about the elders in the two congregations I was associated with. In the congregation I grew up in, the body of elders were lovely (crap public speakers but genuine, kind human beings). To be honest they put up with a lot. I used to hear horror stories about the elders in neighbouring congregations from people who moved to our congregation to get away from theirs!
The congregation I moved to when I left home also had a lovely body of elders. There was one elder that a few people badmouthed as being a tyrant, but he was on my judicial committee and I can honestly say that he was the most sympathetic, encouraging individual. I had five JCs in total and was never disfellowshipped.
That said I agree with Leprechaun that they are not equipped to deal with certain things because they are handicapped by the "official" stance taken by WTS. In my case homosexuality. Despite being sympathetic, they did not understand it (though I could tell they were trying their best to) but ultimately they could only look at the issue through "WT goggles".
There were a few WT study articles in the 2000s, if I remember rightly, with a lot of counsel directed at the elders and how they handle confessions, judicial matters and so on - in summary telling them they had to be a "refuge" and loving and sympathetic (maybe trying to counteract the situation in the 70s/80s, that gma-tired2 described). I can honestly say the elders did all they could in my experience, but in the end that's not enough if the basic belief system is mistaken.
