Sheva was fine for me. Hell, she saved my life a ton of times and took on a couple bosses almost single handedly. She used up a lot of herbs when I wouldn't have, but there was always more when we needed them. As for her getting killed, I turned off the friendly fire. I haven't played with another human yet, and I love the game. Your results may differ.
The co-op aspect is the reason I never played Army of Two. I may buy that game soon.......
