Realistically a lot of other builds should be viable but they live and die by ammo availability because Abilities can't stun Anti-Barriers. Ammo just isn't a thing in Ultimate and because ammo is so scarce you're actively encouraged to crutch abilities and ammo generating weapons that buff abilities not other weapons. It sure would be nice to shoot my guns again in this looter shooter. Radiant in this current sandbox has also lost it's ability to offer weapons Anti-barrier status but it would be very nice to see Anti-barrier abilities. Arcane Needle, Hand-held Supernova, maybe Radiant and Devour could offer Anti-barrier to your abilities. Maybe throw a Blinding burst to around players when they become Amplified so Arc has something. I'd love to see the no Ammo start for Ultimate removed because, and don't forget, we're playing a SHOOTER not a Hack n' Slasher. I'd love it if I were allowed to use my guns. I understand the final patch has shipped, but maybe in the future something comes up and a patch is in the cards for D2. If that day comes I hope the fellas at Bungie will keep this in mind. Until then I guess I'll be a Warlock main and a Behemoth Titan for Ultimate and 5 Feats specifically
