20% + damage
50% + max ammo
20% + range
40% - ammo from ammo packs
no afterburn
airblast only gets rid of projectiles
after 10 consecutive seconds of use you can not use for a 5 second cool down time
1 second delay before firing
all crits become mini crits
10% - weapon switch speed
no damage on enemys in water

Here’s my suggestion for stats, perfect for what the Pyro is unmatched in; hit and runs:

+ Afterburn deals 2% of target’s current max health as damage per half second
+ Airblast is constant stream as primary fire is but at twice rate of ammo cost
- -50% damage penalty

Here’s a graph to show the first mechanic, keeping in mind that all damage in TF2 is rounded up

Current Max Health of Ignited Enemy (h) ---- Afterburn Damage per Half Second for 10 seconds

50 < h ≤ 100 ------------------------------------------- 2
100 < h ≤ 150 ------------------------------------------ 3
150 < h ≤ 200 ------------------------------------------ 4
200 < h ≤ 250 ------------------------------------------ 5
250 < h ≤ 300 ------------------------------------------ 6

Maybe just replaces afterburn with jarate.
Good for w+M1 pyros, better for team hit and runs.

+Does damage underwater
+10 ammo per second underwater
+Makes enemies wet
+Damaging particles briefly linger
-No damage to pyros
-No afterburn

Pros: -50% less ammo per airblast, Works underwater, refills underwater, target becomes wet
Cons: -75% damage, no afterburn

fantastic

"Weapon sprays a shower of scolding hot water and steam onto opponents, dealing damage over time as the water drips off"

Water can effect cloaked spies and other enemies, giving them the wet effect as if they had just emerged from a pool of water.

Can work with neon annihilator, making it basically an axtinguisher.
