If you have not tried the medium map "Gateway" yet, here is the general premise. There are two stars: 1 where all players start and another filled with many resources. There is 1 planet, Gateway, which has the only phase lane to the first system's star. The idea is to control that planet and thus control travel to the resource filled second star system (this is stated directly in the map's description).
Knowing this, I quickly built up a large fleet and took control of Gateway. 4 capital ships, 50+ frigates and assorted cruisers. Phase Jump Inhibitors in place, defense platforms, hangar bays, the whole works!!
The result... it's FUBAR. That's F@#^ED UP BEYOND ALL RECOGNITION in case you don't know the acronym. A whole fleet of enemy ships jumps in to Gateway and my fleet engages. 60 seconds later they've jumped to the star. Their total losses? 1 capital ship (that I ion cannoned to death... I can can't even do that anymore with the 1.02 nerf of ion canon) and a few frigates.
My entire MASSIVE fleet could not stop a small inferior enemy fleet from getting through Gateway. They got to the star and jumped systems.
WHAT IS THE FREAKIN' POINT OF THIS MAP???? Now I either split my fleet trying to chase them down weakening the (laughable) "defense" of Gateway or let them go and colonize the other system (and eventually come back to wipe me out). Actually it wouldn't matter since any other fleet can phase in and out of that system at will without any significant loss at all.
Put simply, phase lane control is broken. Why even include this kind of map when there is ABSOLUTELY NO way to truly control a system and block an enemy advance (or retreat).
Please fix phasing control.
