I don't believe this sentence. What is the reasoning behind it being one of the
best tools vs jedi?
I can name a few I believe are better
other tools specialized vs for jedi? maybe deka pulse. Id agree its better then deka pulse vs jedi. But I think in general its pretty bad vs jedi compared to the two options above.
Well, one of the best. You named three others, and admit it's better than one of them. So it's in the top 3 then, according to you? I think that's pretty good, that's literally 'one of the best'. Also like poison, it needs to be used right. If a BH poison a jedi when they're too close, they can still slash the BH and might have all the FP they need to kill the BH, unless they can move/aim/kick well.
Cortosis also gets completely messed up by a good 3-hit combo which can be done in 1.5 seconds unless the SBD hits the jedi really well during that moment or before they can even connect the first hit. Still kind of a crutch, but not a complete one either.
There's also concussion grenades. I think it's one of the best ones too. Though it can be outranged and anticipated by really good jedi. Generally better than the flamethrower though. But none of these make the flamethrower weak or useless. Especially when the point cost-resource cost-usefulness ratio actually favors the flamethrower out of all these examples.
As explained by other users and partially by myself in this thread, the flamethrower forces a jedi on the move. To pull back or to push forward. Making your opponent move where you might want them to move, or risk taking a lot of damage, that's a powerful tool if you follow it up right.
Even if they simply try to roll to extinguish the flames quickly to deny the DPS, that alone makes them easier to blast at for a short while. A jedi rushing through flames will be open for a counter-attack.
A jedi retreating may save a teammate and put distance between you and your teammates and the jedi that you need, but not too much, just enough to be safer for a moment longer to lower their FP with blaster fire.
