I've been playing Shadows of Mordor during the PSN outage, and I'm progressing quite well. I've recently been finding that there are warlords who are immune to stealth, ranged, finishers, jumps, and normal attacks. The only thing I can do is stun, and get 5 hits, then stun again for 5 more. This doesn't seem to move their health meter. I can use my spirit finisher, but it doesn't do much damage to them, either. What strategies are you guys using against these warlords? I'm considering just leaving them, and not fighting them, because a fight can take over an hour, and they still don't die.
