Please buff engineer drones. It feels like they don't do anything and really s***.

They have a huge hitbox and are easily taken down with a single bullet from any weapon. They do extremely little damage that does nothing but tickle the enemy. They can't mark enemies. And as if you couldn't see them enough with their size, they're also very loud.

The only benefit from it for the millisecond it lasts before it's shot down is a chance to find and destroy a spawn beacon, if you're lucky enough to do so, and if the enemy team even has any snipers.
It's currently nearly useless.

My suggestion is to at least reduce the size, or make it capable of withstanding more than one shot. The taser can actually disable enemies if you don't want to increase its damage. Allow it to mark enemies, and allow it to gain another use from an ammo box like it restocks grenades and rockets.

The other suggestion is to rework it into a fast flying fpv drone bomb you can fly into enemies or their vehicles to one-shot them. If you think this is too strong, then take a look at the overpowered attack helicopter. This is no different, and not as good either. Especially being a one-time use per life.
