Idea for Medigun

The closer to the mate, the faster it heals. Or vice versa.
Just an idea.

Different Trajectory for the Pipes.

The old one is /\. The one I suggest is \/, i.e. it goes down, firstly, then it flies up.
New grenade launcher, probably.

Map of the requests (2nd slot) for Engineer.

You see the images of the requests (Need a sentry here! Need a teleport here!) on this Map.
You can disable somebody's spamming requests (there is an option on this Map).
It could be special 2D Map or special Glasses to see 3D-images (like that ones which you see, while being Trained by Coach).

Gum (2nd slot) for Scout.

You need to charge it |___|
Then, while you have full bar |===|, the second bar is shown and starts decharging.
The less 2nd , the less "hit" of the Gum.

What about stats? I don't know, just a mechanics for this item.
