Yeah there are those situations like you mentioned, but usually most games dont care if was a intentional DC or caused by internet problems. Anyway, loosing an army indeed is a bit extreme to punish those who got DC because internet problems. But I could receive my crowns and it should count as a victory (for profile wins in the future) and also I should be teleported back to world/home map.
PS: again someone quit the match. Ive never finished a siege yet =/
