I really don't need to invest into more armor or defense until an enemy has around 270-300 power. Now, that is not accounting for the bonus from rage, so with that factored in, I don't really need to invest more into armor or defense until an enemy has 330-350 power. Of course, health is still also an investment, which means it is possible for me to go even further without having to actually invest into more defense. As for weapons, there isn't really a point in me to getting a stronger weapon, until more enemies start approaching znake and steelblock armor/hp stats.

As for sentries, it would be interesting if you could hit the bomb back at the sentries. Would make it easier for warriors to kill sentries, so they do not have to corner a sentry to kill it.
