Gotta say I was a bit skeptical about spending the time and points on the live missions (originally just planned to fill them out as I landed cards from the random packs I'd pick up from tourneys or CM games); but decided to give them a shot.... just finished up the last one... and while most of the reward cards don't fit the team theme, the funds they've brought in so far have helped boost the Syrups.... kept the 94 Ted Lyons, the 93 Mel Ott and the Perfect Berra (yeah, he's technically not pre-ww2 old timey, but he's old timey enough

)... working on selling most of the rest...
already sold some rewards and converted them into Jack Stivetts, Charlie Buffinton, Sam Thompson, Deacon White, George Grantham (got him from a gold pack reward), and Larry Doyle (historic pack pull)...
still looking to sell the Maddux, Johnson, Yaz, Cartlon, Piazza, Tulo and Matthews; so that should hopefully bring in a nice chunk to the war chest.
so... yeah... the live missions are worth the effort, even if you won't use 90% of the reward cards
