It’s ridiculous to characterize this as a nerf to spears in general, it’s a handful (I think only the two brought up so far?) that are very cheap and easy to make that are and have always been intended to be temporary tools for use until the player can acquire “real” weapons.
I have zero problem backing off on the rate of breakage.
That is a change, either that or starting a fight with a spear and switching to a different backup weapon.
No one is advocating making all spears fragile, just the two that are literally knives taped to poles.
I’d be perfectly fine to either remove the knife spear altogether or replace it with a fab 2 version that’s not fragile. Neither damage nor speed nerfs either make sense or address the problem.
