I feel that this community needs to share their weapon ideas for Team Fortress 2 if they have any. I'll start:

I had this one in the back of my head for quite some time:

The Krankheit
Level 5 Disease
Class: Medic
Apperance: A throwable bottle containing various chemicals making up a temporary infectious virus.
Slot: Primary

Attributes:
Throw at enemies to infect! Their vision will become blurred and shaky.
20% chance that victims will hallucinate fake enemies.
Infection does 2 damage every 2 seconds.
Infection lasts only 12 seconds.
Self Infection doubles stats on you.

Notes: To keep this item from being op, I think fake enemies should have some kind of vague effect around them, like smoke or something.

PARTICIPATING

The Cure
Level 10 Medigun
Class: Medic
Weapon: Medigun that heals all plague, disease, or poison in no time.
+50% heal rate
+20% Uber lasting time
+50% range of healing
Uber acts as the default Mediguns's Uber
Allows immunity to disease, poison, bleeding, Jarate/Mad Milk, and Bonking when equipped
-10% Speed on user
-20% Uber build up rate
Makes the person you're healing 10% slower
"Do not be afraid. I AM the cure!"

I decided to counter your weapon so it people won't be defensless.

TF2 needs more shotguns. Lots of more shotguns.

It's still a bit OP, considering firing it into a crowd will fill up your metre fast. Give it a firing speed penalty too.

Mate, sometimes to get the job done, you have to forget everything you knew about sinpin', and focus as much lead as you can into a target, as quickly as possible. Believe me, I hate having to do that.
