Recently I and a couple others thought it was unfair to lektrik fan that some exterminators are compeltely immune to knockback. It makes sense to an extent, but as more gain complete knockback immunity, it makes lektrik fan more obselete. So I thought of a buff for it
Basically, instead of exterminators with 100% knockback immunity, they would get a small slow effect instead (the logic being that the knockback might not be strong enough to push them back, but it would still impede their movement a bit). The slow wouldn't be that strong, maybe like a 25% slow for half a second and that would change based of how strong the upgrade is, but it would give something for lektrik fan to do instead of the knockback being sand bagged by one enemy
You could also just nerf lektrik fan so not nearly as many exterminators would need knockback immunity. Idk it's up to you, I'd be interested to hear what you have to say if you want to
