Starting over. I feel lost at sea with all the missions and research. I am also lowering the difficulty this time toCommanderVeteran. The combination of being under-"leveled" (due to researching the wrong things in the wrong order) and better detection and HP from enemies... I ended up with too many wounded all the time.
Also, thank god I wasn't doing Iron Man; not being able to go back and load when you unwittingly started super-hard DLC missions... would have killed me.
I have saved all the soldiers I liked in the character pool. I only have to enable "Random & Pool" when starting over.
