HAWTHORNEPyro needs some reworking, airblast is insane, you can control anyones movement and you get crits on demand with the unlocks (unlocks that won't be banned).
How is not obvious it needs a rework.
True. It should however be balanced in a way to make the Pyro a higher DPS class close-quarter combat/assault class. Otherwise it would make the class useless.
 To the people downvoting me: How would you rebalance Pyro? Taking something away without giving something else in exchange is hardly sensible.
In regards to your edit:
- Reduce the power of air blast, make the knock to a player similar to that of a sticky or rocket. Make it so subsequent air blasts have a weaker effect on players. So you can spam your air blast on projectiles just not players.
- Remove crits on the flair guns.
- The length of after burn is too long.
- Backburner doesn't need crits from behind. Mini would be suffice and still give the weapon an advantage, think of it as a back scatter but for the pyro.
- Degreaser should go back to its speedy self but have a more highly nerfed air blast.
- Phlog needs mini crits instead of crits, and an overheal instead of uber.
- Scorch shot crits you twice if you are already on fire. It shouldn't crit burning players at all with it being so hard to miss with.
- Reserve Shooter needs to go back to 3 shots. Straight up nerf.
- Power jack should make you take proper minicrits like GRU.
tl;dr: Downvote me anyway.
edit: I get it, sorry for causing a shit storm, I'm happy changes are being made.
edit 2: This is not me running away from downvote, I would have removed the whole post otherwise.
