From the last beta I played in, Chapel and Terminal where the only maps available and these maps have a lot of issues. There aren’t any side routs to get out and around the other team. Both maps fallow a linear path past the objectives, paths that are easy to cut off from only a few locations. This happens in Chapel constantly while the EV is on the move and makes defending the wall in Terminal a total mess.
A map like Chapel needs good side routes to get around snipers who are watching the main highway as well as all of the other bit open areas in that map.
There are also many paths that lead to dead ends, such as the path left in Chapel from the defending teams spawn near the construction lift. I see many players, myself included, heading to these locations expecting a route to be there, only to find that there isn’t one.
