if you got rid of the damage or if you added slower firing speed then it would be balanced

Ta Da, slower firing.

Or!
-A large pillar of smoke comes out of the furnace when firing.
-Fires in the jingle bells theme
+75% more ammo
+Enemies drop gift-wrapped healthkits

+Enables festive vision (Candy,snow, and everything else! just like pyroland!)
-Only players in festive vision can see it

I don't really think this would work because there are already so many Festive weapons in the game

My view of the weapon:

Pros:
+On Critical Hit set enemies on fire
+On Critical Hit stun enemies at long range

Cons:
-25% Slower spin-up time
-25% slower movement speed while deployed
-10% Slower firing speed

Overall description: If my suggested stats are taken and put into the game with the weapon (highly unlikely), the mini-gun would serve it's purpose as both a furnace and coal shooter...
Compared to the other mini-guns it's DPM is on the lower side and the heavy has some speed problems with the slower spin-up and slower movement speed while deployed. A Heavy with this mini-gun will be pretty much a downgrade purely due to the fact the bonuses are only when the weapon has critical hits. Thankfully the weapon is highly rewarding while it is crit boosted as not only will it be able to stun long ranged attackers, but also set people on fire at any range! Combine this with the 300% damage boost given by rolling the critical hit or being boosted, and you have a deadly weapon. A heavy with this weapon would pair well with a Kritzkrieg Medic.

has a chance to slow down enmies or freeze them??

(++) Ring of fire
(++) Can use it like a sentry gun
(++) +50% building health
(--) -15% damage
(--) -10% movement speed
(--) When use like a sentry gun: can't take it back, can't repair it and heavy got -100 max hp
(--) Can't upgrade sentry

I thought maybe a Huo-Long Heater reskin, but new stats are cool.

引用自 Gordon the Merchant：

-10% Spin Up Time
-10% Accuracy
-10% Firing Speed
+15% Damage
+15 Health on kill
'Ring of Fire' effect from the Huo-Long Heater (Because it's a furnace.)

DA RESKIN OF HUO LONG HEATER

Catches enemy on fire on hit for 5 second [(cannot stack burn damage; 3 damage turns to 6 damage due to afterburn overlap) fire deals 3 damage and lasts for 5 seconds]
-10% Spin up time
-10% Accuracy
+10% Damage
-25% Clip Size
-10% Slower movement while spinning up/firing
On kill: +15 health

It's actually not...

since there wrapings on the spining barrel, -20% bullet spread or if the wrapings is wool, -10% bullet bread
