I don't know why someone lies still on the ground and wait someone rescue him even next to a Keep.
It's sufficient time to respawn at a near Keep and go back the battlefield.
I think this is the reason why we lost so much today. I will rescue every dead companions as I can. But I hope someone can help himself as well.
I did not mean to accuse anyone. Just hoping we can do better!
Sorry for my poor English. I'm not native speaker.
I hope that I don't make you misunderstand.
