I don't stream regularly, it's just me and people I know on Skype. Too busy at/exhausted from work to stream properly. If I do ever stream regularly, it'll turn me into an alcoholic - for some reason I dislike streaming sober.

You'll need more booze, LW is not just crazy long but so unforgiving. Expect chains of losses/retreats.
My 2 cents from trying LW; Gunners & Infantry all round, those guys with multiple shots & overwatch spec are your bread and butter. Rush advanced beam lasers & advanced armor, get everyone into Carapace armor and a laser rifle you should be solid for most of the game.
Also, when did you start streaming? get many views?

Ayup. I streamed Xcom drunk last year around this time and I have the week off, so why the hell not try out LW as I get increasingly unsober? But I figured I may as well get a little way in first, so people aren't bored by the opening missions when I stream tomorrow, assuming I go ahead with all that.

Looks like someone's gearing up for a Long War
