Pay a visit to some of the busier stations on the GN route particularly in the morning peak, and you'll see the issues this is causing. First class passengers quite simply don't know where to stand, whilst standard class passengers have the issue that there are two doorways out of every eight (e.g. one quarter of the train) they need to avoid if they're going to have a chance of getting the seat they want, or perhaps getting a seat at all. Because the fleet is currently divided in which way units face, there's no certainty from one day to the next. As an aside, this is also bad for those who need to utilise the accessible space on the train - as the position of this varies too.
As has been emphasised before, the 387s already have considerably reduced seating compared to the trains they have replaced, it then makes things even worse to have introduced a boarding lottery.
Meanwhile, despite avoiding them as far as possible, I've now experienced two class 387 failures since their introduction. In 20 years of 365s I've only experienced two failures, both of which were rectified within a 10 minutes. The 387 should be a relatively proven design, although maybe crews aren't fully familiar with them yet.
