Bloodlusting is probably the strongest trait right now, as when paired with extended mags, you can pretty much fire indefinitely. At 25%, it was way to weak. At 50%, it's far too strong. I think rather than going back and forth with the numbers, a good fix for this would be to have the added ammo pull from your reserves. This would mean that pairing bloodlust with extended mags is vulnerable to running out of ammo. The best way to offset this would be to use capacity, which would be at the cost of extended mags. It's a nerf either way, but wouldn't put bloodlust back into the ground like it was at 25%, and it gives some love to capacity.
