Melee only gadget concept: The Jammer
I've decided that since so many here seem to think that Shockwave shutting down melee from using any gadgets/specs to survive/close distance, then it only seems fair that melee receives its own version of the concept.
Introducing, The Jammer (you must always include "The" and make sure it's capitalized) gadget. It is exclusively available to melee weapons. What it does is simple, you pull up the tablet, point a cylinder shaped hitbox(be glad I didn't decide on a cone or an AoE blast) at the target(s), and click.
This forces all targets to reload their guns. The reload is a bit slower than normal (maybe 20%), due to the player having to clear the jam/fix the malfunction. It could also be funny if it forced weapons like the Bow and Throwing Knives to wait a moment before attacking when hit due to them dropping their current arrow/knife...bundle? Have then jam their finger or something so that I don't have to think of a new name.
Now because I'm trying to be reasonable, it would probably only have one charge. The CD shouldn't be particularly long, though. I'm not going to put an exact number because I know that's the only thing some of you would focus on. We're thinking bug picture here.
So yeah, if Embark adds something like this to the game, I won't complain about Shockwave having a 2 second long glitch. Honestly, I'm almost being too kind considering the targets would still be able to use their defensive utility and kick.
