Squads still get singled out and sniped

Singling out single squads among several in the same sector among one player is supposed to be prevented, yet there is a loophole around this: if you attack an ally and they have less squads than you, other players' squads will automatically be sucked in, even if it results in a squad split.

Following on from this, can we get the precise rules for PvP and guild engagements written out somewhere? I thought I understood them from previous discussions on this forum, but recent adventures have demonstrated that I didn/t.

I'll make a note to write up detailed rules on the wiki. It is very complicated code because there's a lot of potentially complex situations.
After the next big update there will be better on-screen information that helps you make PvP decisions.
