The point of the damage cap?

It's the same as the meso cap, they assign a maximum number of bits to contain the damage information. For our current cap it's probably 19 bits so it can go up to 2^20 - 1 which is roughly 1m.

it has nothing to do with programming, it's purely arbitrary. it used to be 99999, then it was raised to 199999, and so on as balance dictated, and continues to do so

edit: didn't see how old this post was when i responded to it..
