That doesn’t follow, if there are other legitimate reach weapons, we can certainly add them, but we aren’t going to add made up weapons just for the sake of variety.
I didn’t say they would be hard to use, I said they wouldn’t deal much damage. It’s a matter of how much momentum the terminal chain segments have, which generally is not much.
I don’t buy either of the nerfs in the OP, both are contrary to how zombies are supposed to work. There are other zombie buffs I have planned, like making pulling individual zombies harder, which would help a bit vs kiting, and there are various other nerfs and buffs that might help indirectly.
As for reach weapon variety, feel free to make specific suggestions, ideally with stats and references to real world weapons to justify them, and we can look at adding them.
