I don't really understand. Having more "choke points" is a good thing, not a bad thing.
When there are only three dividing a map in half (Vire River Valley) the game is a nightmare. But if the whole map is comprised of different possible routes, there's no way to lock it down completely.
I've never felt pinned behind a defensive wall on Trois Pont or Ettelbruck (in 2v2 at least)
What he means is not to get rid of chokepoints , if a map however is heavily domiated by chokepoints it maked maneuvering units very hard , therfor the maps very campy.
With few chokepoints he means to get rid of some completly in order to create a more open field
and not to create fewer chokepoints as in getting rid of some by closing them etc.
I hope i got that right
