Yeah, the corridor meta can go die in a fire as far as I'm concerned. MBTs are already strong enough in PvE, they don't need to have the maps tailored for them too.
As much as people hate Moscow Calling 3 for the delivery mechanics and a single player being able to screw over the entire team, it actually has the best map of any spec ops mission imo (probably because it is a full PvP map with minimal modifications). The objectives are far enough apart that they don't need physical barriers (like buildings) isolating them from the rest of the map, there's plenty of open space for squishies to do their thing, while still having enough hard cover in parts of the map for MBTs to be able to keep their flanks covered. All told, it's a good map for a mission that gets hate for the half-polished game mechanics that came with it.
