The fighting lion is practically useless after the nerfs.

It reloads slower than a tortoise without the catalyst and is still fairly slow even with the catalyst. It’s maximum damage of 144 (without the consideration of light level advantage) makes it an extremely gimmicky weapon that doesn’t seem worth the effort to get mediocre kills via. switching to your kinetic weapon. Which is practically the only option given the previously mention slow reload speed. Overall, the weapon needs some kind of buff, wether that be Reload speed, Damage, or just a more reliable AoE. And it’s infinite ammo is pretty useless if you’ll only be firing it once every 14 years. It would definitely just be better to use a special ammo grenade launcher if you’re planning on using one, or the Hard Light if you’re in it for the wall bounce.
