My Stat Ideas are:

Pros:
+ On hit 3% Faster Healing with the Med gun (Max. 10 Hits)
+ Taunt Kill Refills your Life (Regenerating while Enemy is Stunned)
+ Right Click Stops the Bleeding of your Teammates (when you Hit them)

Cons:
- 33% more Damage Penalty
- 20% Firing Speed
- Deployment Speed Degreases by 25%

You can change my Stats if you Want to :3

The Big Sister's Sting

+50 firing speed
-25% damage penalty

it should have some sort of effective like gains uber on hit but only if you hit them in the back unkowingly stealing there "adam" hehe. or maybe make it so insteand of a mellee weapon it works as a syringe that sucks blood(Adam) out so you continuously hold the m1 buton and as long as your connecting with an enemy it drains theyre health an returns it to you in uber. its based on the little sisters harvesting adam it should be based around doing less damage but draining enemies for there adam, and perhaps since this would make it be less useful as a weapon it could have a +25 health attribute or maybe increase damage resistance but only when its out not as a passive resistance.

+30 health on hit

25% slower swinging speed

+20% deploy speed

how about

On hit: 15% ubercharge
+35% firing speed
+ the more ubercharge you have, the faster your firing speed and the faster you are
(Can become up to 20% faster and 30% faster firing speed)
-15% damage
-When active lose ubercharge by taking damage (lose all ubercharge by taking 150 points of damage)

any good
