Omg! I just beat the Rescue Meridian mission by killing everything then rescuing her, without any casualties, or even anyone close to dying :DDDDD (Well, one exception; Gavrielle almost died to a bow counterattack)
This was also with the whole map after me at once.
I have it recorded, but it's a beast of a video (Just under 2 hours long [the longer you play a mission, the laggier it seems to get for some reason- memory leak?], and is ~125GB lol). I'll upload it as soon as I can, and post it here. I just love the tactics available in this game. The general premise I used was holding up at the bridge, and using the water very very effectively, especially with an amazing combo by Louise and Emma to deal with the lv 16 Pyrokineticist.
One other thing that helped considerably is one thing I learned during this mission: If one character makes an attack which makes them level up, they can both move a couple more spaces afterwards and still make another attack. In one case, I had my crossbowman get FOUR attacks in one turn (one of the extra attacks from Motivate) because of her finishing off low health, high level enemies. Emma MVP this mission with her Motivate ability. [Edit: Oh, turns out that leveling extra attacks were a bug and are going to be fixed in the next patch; oh well]
