Honestly, skirmish format is better, but it isn't what is keeping me out of Legion.
Like with X-Wing, which I stopped buying a little while after I started, the wacked out decision making of FFG of what to add to their Star Wars games and from where, makes all their games look less like Star Wars, and a lot more like somebody's personal game based loosely on Star Wars, even though the source of each miniatures comes from a book, or a video game, or somewhere.
Extended Universe people are the ones who seem to like this version of a Star Wars game the most. I personally can't stand it when I see what the games look like. I get the never ending release schedule as FFG tries to grab as much cash as it can from its game. That bothers me too, but less so, since I know they're looking to milk this like any other company does.
That's the problem I don't really see changing for me. Skirmish does help. But it's more that when I look at what FFG decided to put in its list, ships from esoteric books and video game for X wing, and units from those same things, it doesn't appeal.
