Thinking does not mean knowing.

First off, anyone have any? It's good to make suggestions for TF2 if you can't use the workshop itself.

A few ideas I have myself...

Bubble Bomber:
Level 10 Grenade Launcher
Fires floating spheres that hover in the direction you shoot them
Alt Fire: Cause it to seperate into smaller spheres which explode
-75% Fire rate
-25% Damage penalty

The Clean Sweep:
Level 5 Broom (For Scout)
(Held with both hands)
On Hit: Knocks enemies back, similar to the Force-a-Nature
+50% Walkspeed
+30% Fire rate (Swing rate)
-80% Damage penalty

Freedom Fighter:
Level 8 AK-47 (For Soldier) (Very similar to the Sniper's SMG)
Alt Fire: Throw a grenade in the direction you point
+20% Damage
-45% Ammo
-20% Fire rate
Must wait 45 seconds before throwing another grenade
Does not fire rockets
