Pikes were used much the same way right? Surprised I never put the two together, ancient humans weren’t stupid so of course they’d realize that was a better way of causing harm than just throwing it. Not to mention their use of leverage in weapons like the Atlatl. No clue on the timespan of these things but I do find this stuff interesting.
Yeah, if your main form of offense/defense is that you are: large, and have massive fuck-off tusks on your front then charging seems to be a pretty good go to.
