SEOW HQ:

I see lot of action still going on the SEOW front. Lentolaivue 34 currently participating in Marianas.
As for mods killing SEOW: HSFX was purposefully created for SEOW. Don't know personally what it exactly does, suppose something to make SEOW work better with the game. But really, I don't care. Campaign needs this and that mod, I install them to get to play. If one wants to play, he/she will go to great lengths to play.
