Firebugs left side on perks to me is very underwhelming compared to the right side, for the most part. It's not to say they aren't useful, they just can fall short of anything the right side has.
My idea on what to do with the left side
Level 10 smoker
Zeds burning for 5 seconds will start to take smoke inhalation damage and leave a damaging cloud behind after the zed dies.
Level 15 flametank
Receive 10 percent less damage from all sources and increase carry capacity by 3.
Level 20 Burning Aura
Release a burning flame in a 360 around you every 5 seconds.
