Wait, what? Doesn't not using this feature (if it exists) kind of obviate the point/idea of being lazy?
Actually, I just checked again, and it seems like something being worked on and not yet in the build:
https://openxcom.org/forum/index.php/topic,4747.0.htmland yeah, there is Lazy, and there is LAZY. As in, I'm in the latter category.
I usually go through and add necessities: Smoke grenade (primed, on the leg or belt), bandage or Rum (for healing), handle or other close melee weapon, and a blackpowder/etc, on all the gals. Then I try to match shooters, melee, and throwers to weapons. This may involve changing out armors to enhance these fighters. Once I've done that, I don't have real, "standard shooter build" etc. Often these are different due to carrying capacity and armor available.
So I haven't gone with Meridian's approach of making universal soldiers: Everyone gets Defender Armor, an Autogun, a Sniper Rifle, A tech blade, and some grenades, with 3-4 archers as an alternate build. My crews tend to be more diverse in the equipment deployed, so saving all of these different ones as templates hasn't made as much sense to me.
As far as the Mansion goes, a crew of 8 could do it as a snatch and grab. Work your way to the treasure rooms and depart. I would never try to sweep the hole thing with 8, unless you are Very Patient and have Loads of time.
