Hmm, I could imagine Bs| & TBH alliance, but it would make much more sense if they fought against Nomads instead of Liberty forces. There is not much RP background to justify Corsairs attack Liberty. So Corsairs would have to defend themselves against Liberty forces - and I can't help here because I don't know rumors and news from the other side.
It makes most sense for corsairs to attack Bretonia, Outcasts and Red Hessians. They should try to benefit from the Kusari/Bretonia war. and they should be fighting Red Hessians before they can continue spreading into other houses because they are blocking many ways. Even the Rheinland invasion event (which we had a month ago) wasn't planned correctly as the main purpose of the 'Road to the Rheinland' news was to attack Red Hessians from behind, not to invade Rheinland.
Having events 100% alligned to FL story is nice, but the situation on the server doesn't always enable us to do it. It's always a compromise. Right now we would need a lot more people joining RHA, SF, QCO and KNF. Then we could have amazing Events connected to each other for a lot of factions.
OK, back to the topic, I am not against, but I'd prefer something else...;)
