Lost Legion has been doing everything independently by themselves! The only time Hospitaller gave us anything was when they gave me Bulugur to just raise S&D and give me a title. That was when we were KUTT/Twelve Hands. When Lost Legion reformed, they took it back and haven't given LL anything since then. FCC's involvement in this war is NOT necessary. This is an Old Blood Beat Down, it's a fair fight all around and LL has been sitting, waiting, and working their asses off to make a move like this.
Don't blow their come back, these guys have worked very hard to do it. Literally, I did nothing while in the Strat Faction except spend Production Points on a daily basis--these guys did everything. To be exact, 4 of them did EVERYTHING. Slim, Flowers, Greatsage, and DooM did all of the micromanaging of Strategus. Also, Greatsage has spent nearly 5 months with his friends in EU territory making small trades of only 300-500 goods at a time with approved trading routes. They funnel that gold back over to us to help out. Not that that's any of your concern, but it's the reason you've seen a large part of our armies grow fast.
Also, not that it really matters, but if anyone was benefiting from Hosp, LL relationship it is Hospitaller. Flowers and crew are forced to buy their gear, and in turn, Hosp gets their 5-15% tax rate since LL only have one fief at the moment and is looking to expand.
TL;DR Leave LL alone and let Teutonics and LL duke it out you cotton headed ninny muggins.
Added: In Response to Jack, a lot of the KUTT guys that haven't been playing for a Long Ass Long Fucking Time but set their troop caps to 2000 just came back and we all gave LL our excess troops. THUS this is why they have so many more troops for this war now "seemingly over night"
