It is FFA PvP if you Exile. Tarinax is Factional PvP with Exiles; this way, everyone's happy. Exiles can kill anyone from both sides, and even each other. Kander was talking on Discord about a fast Exile (I'm assuming it'll be via a Priest of Discord NPC-- the Freep one was in SFP, in the Guild building, during Seasonal, but we'll have to wait and see).
Please explain what is FFA? I don't understand much English, so just decipher this combination of letters.
