We all know this build by now BUT Bungie did something amazing with Fighting Lion.
It now apply Volatile on direct impact! I think its better to use this build with FL then with the new grenade launcher exotic Alethonym.
I don't think I need to tell you all how this build works. Just know that you can play a little bit more aggressive of the Frost Armor and amount of Heavy Ammo you will spawn.
Res: 100
I would not worry too much about Recovery because it's either you Freezing the enemy or you having a bad time. But if you can: 100
Discipline: 100
try to fit in all these mods. every little bit helps. If you dont have enough mod room to fill in, think about lowering your recovery like i mentioned before.
Use whatever Kinetic/Heavy weapon you want. You can use something that has Incandescent and Strand (Threadlings)
Note: even tho FL applies volatile it does not seems to work with other weapons and to break Barrier Champions shield. They will surely fix this issue. Once fixed this build will have alot more potential.
