Still a fighter needs teammates, on whom she can rely on when there's the need for any sort of support. As a lone soul, the ability to be hopeful quickly dissipates.
And most importantly, my teammate doesn't think similarly as I do. That for him I would do anything but it apparently isn't a two way thing.
And I sense myself losing my hopefulness. And that is as bad as being a fighter who lost her weapons and shields. She is now a fighter who enters battlefield knowing the chance of failing and dying ingloriously is high, but that's what she wanted. An end to a hopeless fight.
