About Suppressors

The suppressor attachment for the muzzle has too few drawbacks—doesn't this narrow the range of attachment choices?
Simply equipping the low-cost suppressor grants a significant advantage in combat, but I feel the benefits outweigh the disadvantages too much.
If equipping a suppressor provided sound suppression but also significantly reduced bullet velocity or fire rate, wouldn't that create reasons to choose other attachments, thereby expanding customization options?
