Normally, I just walk away from those unkillable tank builds. However, yesterday, there was one who found himself inside the walls of a keep we controlled after pushing his side out and rebuilding a wall. His side was still outside sieging and we were inside counter-sieging, so he spent his time walking around setting our siege on fire, completely and utterly ignoring anyone who attacked him because no one could put a dent in him. All we could do was follow him around putting out whatever siege fires he started. It was the epitome of troll gameplay.
We needed him to die, but there was no apparent option to make that happen. So, what are y'all's tips for this sort of situation when you can't ignore a tank but can't kill them either? Is there still a strategy for eventually killing them? Is there a way to troll them back? Or are you just stuck with a completely broken gameplay situation?
