I think the dev added in the disengagement ring to overcome the primacy of railgun cruisers and battleships. They were just sending out suicide frigates to pinpoint enemy ships and then deleting them with railgun rounds from the edge of the map. I get the need to overcome that but I would rather he addressed it with something such as better jamming, slower railgun round travel time, the ability for ships to jink more with lateral thrusters, or defensive weapons like sandcasters/shotgun missiles that could intercept railrun rounds at high relativistic speeds and defeat/deflect the rounds rather than artificially limiting the battlespace. Oh well. I hear fighters will be added soonish. Perhaps a few squadrons of space SPDs will give the battleships something to worry about.
