Kit idea: Thrower [needs different name]

Starting items:
Stone axe (yes, Jackhammer has a stone axe, but an iron axe would be too strong for combat)
Kit abilities:
If you right-click (!) a stone axe, you will hurl it with great might. It flies a certain distance (I'd say about 10 blocks) and then lies there, with nobody being able to pick it up. It then despawnes, unless someone other than the Thrower steps on it. The axe can be bounced off of blocks (e.g. the Gladiator box wall).
Effect of hitting someone with the axe:
If you hit someone with the axe, they take 2 hearts of true damage (is damage that is not stopped by armour or Boxer, the only kit able to stop that is Turtle) and 3.5 blocks of knockback. If you hit with the axe, you have 4 seconds of cooldown before you can throw your axe again (it stays in your inventory, it simply spawns another axe while throwing). Missing results in a 7 second cooldown.
If someone walks onto the axe, they are thrown 5 blocks into the air and take 1 heart of damage plus whatever fall damage they would have taken.
Pros:

• Excellent kit for some extra damage in close-quarters fights
• Nice damage
• Can be used to knock people off of a tower, or a team member into a ravine
• Need to refill in a Gladiator match? Just smack the Gladiator away with this and recraft/refill to your heart's content (@Mattyz_ is gonna like this)

Cons:

• No anti-fall damage
• No mobility
• Can hit teammates with it
• Only has knockup if someone walks onto it

???
Explain please.

Or just remove Viking because it is too overpowered and the only counter is Boxer?

 

Good.
Now, about Urgal...

 

Oh I'd be abusing the hell out of this

 

(sorry4bump)
Diamond axe is too much, you're able to use it 3-4 seconds after the throw again (if you hit). That's pretty nasty, and 6 hearts of true damage in a full iron fight is utter overkill.
That being said, I agree with @NooMatt that maybe Viking could be nerfed and get this idea brought in.
