Regarding Gwent I would give an entirely different answer today as to that I would have given only a few years ago. They were appallingly bad, in fact words fail me as to just how bad they were at one time, but they have turned it around and for some time now they have been really quite good. Helpful friendly and generally very knowledgeable are the words that presently come to mind. Perhaps not perfect but getting there.
A friend has recently crossed back across the river from bear country (Glos) and was well relieved to have done so as there is an entirely different attitude over there.
