Ok just an Idea

-50% Clip Size
-25% Base Damage

Each shot has to be charged and time to get the correct distance (Similar to the Sticky Bomb Launcher)

Every Rocket causes a small nuclear explosion that affects all those in range.

With Friendlies:
Gives 10 seconds of 200% Speed

Enemies:
Decrease Speed by 50% for 10 seconds

While Kritz

Friendlies:
10 seconds of 200% Speed
Gives weapons mini crits for 5 seconds

Enemies
10 seconds of 50% Speed
Enemy is marked for death.

Just some suggestions, I had Payload and MVM in mind for this.

i think it shud have a larger blast radius like a musroom cloud and +25% damage but only one in a clip

No random crits
No knockback
Alt fire: The longer you hold down the faster your projectile is to a maximum of 200% faster projectile speed (It takes 2 seconds to charge it up that much)

+25 blast radius
-15 damage
if hits freindly gives bonk atomic punch for 5 seconds

Pros:
+10% bigger blast radius
Alt-fire: Can shoot small portions of bonk energy drinks. Given to team: they get mini-crits for 2 seconds and move 10% faster for 5 seconds. Given to enemy: they get dealt mini-crits for 7 seconds. (team mini-crits with dealt mini-crits togethor causes +20% damage increased crits, basically instant kills)
Cons:
-50% clip size
-10% reload rate
* cannot equipt the following when this item is equipted: Buff Banner, Concheror, and Battalion's Backup.
* cannot rocket jump
* cannot alt-fire yourself
-25% alt-fire projectile speed
-100% alt-fire clip cost (uses both shots to alt-fire)
-50% health refill from healing sources (dispensers and pick-ups, not medics)

-75% blast radius
+25%reload speed
+25%firing speed

alt-fire stuns enemy

-projectils are not explosvie
-+30 reload speed
-when fired at team mate has a %50 to heal them %10
-no recoil (no rocket jump)
-faster projectile speed %50
- -25 less damge

+25% explosion radius
-25% clip size
Projectiles affected by gravity

you are invulnerable (just like a scout) while rocketjumping
-15% damage

voila

why do you people have to make 2-pages-long stats didn't you learn anything from the scottish resistance incident?!??!?!!?!?

Pros: Invincibility for 4 seconds after rocket jump
On friendly: 1 second of invincibility (as any more would be op and really annoying if your team mates don't want to lose their weapons the entire game)
On enemy: Stun time based on range (Long range minicrits)
0 knockback from sentry guns
Direct hits do 60% increased knockback

Cons: Minicrit damage does -100% dmg
-30% dmg on buildings
-40% dmg
-30% blast radius
-50% Reload time + Cannot reload until both bonks have been shot
-50% Clip Size

Alt Fire: Stuns for 3 seconds, enemy - 100% uber if hit.
Alt Fire while projectile is near enemy: Changes direction towards him (Uses other rocket in clip if not used already)

Hidden effect (Like flare gun crit): If direct hit on friendly scout with bonk equipped, increase bonk time by 3 seconds

I'm thinking a really new-concept looking gun should be given really new-concept situational stats.

Ok, so here's my idea.
Instead of rockets, it uses charge power.
Primary fire shoots a can of armed, explosive bonk. More damage and radius, with no random crits and less projectile speed, but deals crits where it would normally deal minicrits. Uses up 50% charge.
Secondary fire shoots a can of armed Crit-a-Cola. Less damage, but faster projectile speed and, on crit, marks the target for death for 4 seconds. It would deal minicrits whenever it would normally crit. It uses up 25% charge.
-20% reloading speed.

it will be like the cow mangler except that when u charge it and shoot it,
it will make the player wet

Stats: 10000 damage penalty
SAME ♥♥♥♥♥♥♥ STATS AS BONK, LOL

-25% damage
direct hit stuns for 1 second
150% ammo capacity
-20% reload speed
