The flamethrowers arw so weak early game but when you focus them for a little while, especially with the draconic salvo arifact and upgrades, they become crazy strong. Probably my favoirte tower behind balista.

Yeah, flamers scale ridiculously hard. Things will keep getting balanced as more stuff gets added/adjusted, but I am also planning to make most weapons a bit stronger early, so it doesn't feel they're just scratching the mountain if you don't have a lot of upgrades, and to also speed up the early game a bit.
