I agree whole heartedly with that. Thats why I am more of the mindset that the FT is fine the way it is, with being able to have whatever weapons and gear on their loadouts. Its also part of the reason, aside from just lack of testing, that I dont speak much on FT weapons.
But having the pred weapons be more purposeful rather than different iterations of melee, is more important, because the pred has only himself to rely on, and as such, his weapons should fit his playstyle directly. Not just be the best for the sake of being the best. But have true purpose to each build.
