I'm back! (with a gun idea)

[Crypt2c]

So the idea is a godlike MP5 named entropy. Here's what I'm thinking:
-10% fire rate
15% damage
20 round clip (not sure what the default is)
20% accuracy
8% movement speed

1 in 8-12 chance for your bullet to deal 50% damage
1 in  7-10 chance for your bullet to deal 200% damage
1 in 10-12 chance to force your opponent to swap from primary to secondary or vice versa
1 in 12-14 chance on hit to cause your opponent to to lose control of a random movement key
(forward, backwards, right or left) for 1-2 seconds.

What do you guys think?
