That's why I hate doing the Cure. Apparently no one knows have to use their abilities, especially cruisers and science ships, who don't heal. Lately, I have only got the optional once in six times trying the Cure. The Cure used to be the fast and quick one, but now its populated by morons, who don't pay attention to the time. The last time I played the Cure, two cruisers, a science ship, and an escort failed to protect the Kang, with me fighting against the Cubes, and they blamed me. Before the massive fail rate, I don't die on the Cure nor normal Infected.
I only go on Infected Elite, and generally I get good PUGs. KA, I get too annoyed with the non-team work. I played with this one guy who let in four probes because it wasn't his job to destroy them. Apparently his job was to fight the spheres, self appointed.
