Yes, I support your request to make the cavalry bots, especially final bosses, much weaker. Cavalry mode will never provide as much xp and/or loots as it is meant to be a side project, so don't bother asking for this. But making the complete run shorter (by nerfing the bosses a lot) would make it, at least, more funny than painful.
But next time, aim at the head
