That is literally a straight downgrade to the Gunslinger.
My proposition:
=Replaces all sentries with mini sentries
=Sentries are manually controlled
+Sentries start at full health when placed.
+200% Build Speed
-Sentries disabled while inactive.
-No melee attack.

Just to be clear, it would not add the shield and fire speed of the Wrangler, but it would place minis extremely quickly, making it a good tool for doing a lot of damage in a small time, but would still have the engie as a light class. This would be a good tool for ambushes and killing other light classes quickly, but would put you at a disadvantage against an explosive class, heavy, or pyro.
tl;dr It sacrifices area denial for a quick way to output a lot of damage.

Hate to burst you guys' bubble, but I think this is meant to be a cosmetic...

nope, cosmetic. it's on the engineers left hand

Before you say it's just a cosmetic, follow me here.

Wrangler re-skin.

Level ### Glove of Power

When active:

(+) reticle appears that locks on to nearby targets; reticle can detect cloaked and
disguised spies
(+) 150% sentry damage increase
(+) sentry rockets home onto targets
(+) 200% sentry accuracy increase

(-) on primary fire, you will be vulnerable for 5 seconds as you mash the buttons in vain to try
and control your sentry
(-) not compatible with sentries, mini-sentries, or disposable sentries
(-) no random critical hits

+9000% bad
-9000% virginity

i was thinking more of a pda

This is a cosmetic, or a idk Re-skin for wrangler or short circut

@Facuet it's a cosmetic didn't know at the time

this would be a cool PDA reskin, especially since no pda reskins even exist yet

@Heavy Weapons Guy what about pip-boy? it changes the look of the pda.

This. And not just a simple PDA. Hi GPS's balance mod added a speed pad that replaces engie's teleporters, so instead of being teleported, you get a speed boost when you step on it. This gives engie a useful add-on to help his team reach the front lines without having to build two teleporters and without overshadowing the original teleporters. It'd be awesome if he could build one of them by having a new PDA.

I'd also add a mini dispenser that builds faster, heals as fast as a lvl 2, but has less health and gives as much metal as a lvl 1. This would make engie less of a turtling class.

how about + 500% jerking off speed

or

=Replaces all sentrys with mini sentrys
+increases health to 140
-10% lower firing speed

I know the stats are a little bad but this is my first time doing this

how bout
=Replaces dispenser with mini dispenser
(when held)
+ 10% increased walking speed
+ 10% knockback Vs. enemy player

- -25 Health
+ Mini-Sentries cost 80 metal
Can build two mini-sentries at once

Maybe more or less health. Maybe different costs, like keeping them at 100 metal.

why cant it just be a cosmetic?
