Civ mechanics and cores - something to consider

One mechanic I don't yet understand (as I'm not sure if it's come up this season) is what happens if a faction member from a different civ than the faction leader destroys a core. I think it is important to consider this. In terms of civ leaderboards, is it based on faction (leader) civ, or is it based on the individual player's civ? (what civ gets the point) In terms of fac leaderboards, is it based on faction (leader) civ, or is it based on the individual player's civ? (if the faction gets a point or it's a same civ raid so no point) In the case of faction, if it was based on player civ, that would mean that a faction with members from 2 (or even all 3) civs would have a MAJOR advantage over a faction with members from only 1 civ, as then they can get points from cores from ALL civs, rather than only the other 2 civs.
