I mean, why not just have 6 choosable perks, 3 selectable attachments, but they still take away from your 10 points? I don't see why you have to spend a point on a wildcard, and then spend another point to choose what will be available after using the wildcard. Someone help me understand this. I think it's just really stupid.
I think Overkill should be the only thing using a wildcard.
I think certain aspects of it are dumb. Why are there perk tiers with the wildcard system? I can't think of any overpowered combos were the tiers to be removed, especially when the already existing wildcard system allows for a combination of the ones people would already consider optimal. Just remove tiers and allow us to use wildcards for an extra perk, not an extra perk within a tier. I'd much rather have Flak Jacket, Lightweight and Ghost than an obligatory perk 2.
