Long range melee weapons like spears or forks have a huge stopping power as history teaches us. Think about greek hoplites or medieval spearmen, infantry departments capable to stop a heavy cavalry charge. That said, I think it's time to think about a spear or something similar with interrupt, cause that trait represent exactly what I'm talking about. We can find it useful against special walkers a lot 'heavier' than regular ones, like fatties, goos and spiked. I'd say that a certain % of interrupt should be fixed on that kind of weapons, and I honestly think that it would be a bit OP but also way more logical and historically accurate than other weapons. Actually, considering the tactical spear, assuming a fixed x% of interrupt, you would take fully advantage only against special non stunnable walkers when you can no longer back off and repeat.
