That’s one of the most interesting ideas for Brute’s nerf.
However, as a dual Spartan Carnage user, I feel its 3 shots aren’t enough, so I compensate with an extra Nightfall to ensure I’ve enough ammo. With a 2-shot Spartan, that would be a useless weapon.
If a 2-shot Spartan (nerfed Brute) exist, I rather use something else, like a Night Eagle. After all, a Night Eagle is 3 shots, hence making it better than a 2-shot Spartan.
If you want to make a comment, please make sure you’re aware of what you’re talking about, talk from experience rather than conjecture. You also need to think thru the damage.
And no one has an issue with heat and energy versions of the Frantic. The simple matter is there are better options than using those weapons. I almost never see those weapons being used in the arena, so there’s no point in discussing a nerf on them.
