No more so than the hex system. Currently its rare to see an empire cap a cont with anything under 50% of the population. I don't have a very high end system and have never had any major issues. It just makes it a lot harder for individuals to constantly flit around undefended territorys, ignoring terrain and defended bases totally. Its still possible to back cap and cut off using the lattice, it will just take real skill, not just the ability to crash land an ESF in the nearest connected undefended hex. Hex reduces the potential scale of PS2 to that of at most of platoon vs platoon, makes defence a waste of time, ends good battles prematurely, makes the terrain useless, negates any prepared defence, and thoroughly bores many people.
