I agree about LX. ZRH used to be such a good place to connect until LX cut the frequency down to 2 a day. Now you often find that the connections only work in one direction.
I think that MAG should give at least as much attention to beefing up frequency on existing routes as it does to getting new destinations. There often seems to be a "flags on the map" attitude to route development at MAN, whereas connectivity is just as much about schedule depth.
