If you're referencing the frontline martyr tactic, its... Ridiculous. I mean, where in the hell would an entire army fire at a single noble's unit and ignore a battlefield full of warriors? It just doesn't make the slightest sense.
This tactic has done a great job revealing a tactical/technical fallacy in the combat code that must be rectified as soon as possible.
I wasn't, if you are talking to me, but I also deeply despise that. Not sure what the best fix for that would be though.
