I don't like the electro staff trooper. I think it's a dumb idea. I've read the speculation in the threads about the need for troops trained to fight Jedi. It just doesn't seem consistent to me. Rey obviously thinks Jedi were/are a myth from what we've seen in the trailer.
Why would a military invest so much resources into training and equipping soldiers with a weapon that has little likelihood of ever being needed escapes me. Plus a real trained Jedi could cut these guys down easily. The concept seems unnecessary to me. The clones didn't need these weapons to kill Jedi when Order 66 was initiated. They shot many Jedi down with blasters.[emoji12]
