Jacksons are raped by jp4.
Firefly instantly kills jp4 with normal attack + rockets.

FF role is not to fight tanks in prolonged fights. Relic actually did a very good job making FF very good niche unit instead of copy-pasting it into another long range low survivability TD with different model and slightly different stats.
Without the expensive rocket strike ability the firefly is severely overpriced.
The firefly is far too dependent on the use of a 100 munition ability that require a 50 munition upgrade to use. Yes the ability to deal 240 +240 + 200 damage is insanely powerful but the firefly is a cost ineffective unit otherwise.
no one likes to fight against a 680 damage alpha either. Lower cost of the firefly to 350 mp 125 fuel. lower the rocket attack to 2x100 and cost per use to 60.
Not once while using that tank did I say "huh, this is pretty underwhelming, it only absolutely wrecks medium armour at an excellent rate as opposed to fantastic, and its 90% penetration rate on the kingtiger is sorta meh."
the firefly have similar penetration and dps to the panther. The gun is very good but by no mean infallible.
even at blank point range, the firefly's 260 penetration only grant 69% penetration chance against the front of King Tiger. 90% penetration rate is an exaggeration.
the firefly's 200 damage is also wasteful against medium tank. You need to spend an extra reload cycle (10 seconds) to fire a fourth shot at the last 40 hp of a panzer4. This is something the DPS value doesn't reflect.
The panther need ~ 22 seconds to kill a medium tank, assuming it enter combat with a round in the chamber and all shots hit and penetrate.
The firefly need ~30 seconds to kill a medium tank under the same condition.
