it's surprising how many people forget that they don't have a tag enforcing 1:1 retals in this server. The reason ss and ps retals are the norm in alliance, ffa, and team is because they are enforced by the alliances. An alliance will go to war over 1:1 nuke or chem retals for land grabs.

A missile or two, three or four special attacks - these can be valid retals for landgrabs on this server, because there is no unified authority enforcing retal rules.

You don't just retal to get your land back, you retal to make the next land grabber think twice. A valid retaliation is anything up to the point where a land grabber decides to stop netting and fight back.
