Especially since blasters wouldn't have recoil.
What does that have to do with ADS?
It would make aiming easier (especially in burst fire), so the run and gun style of classic shooters would be more feasible.
Admittedly, sights would still make sense on guns, but my issue with the mechanic is it promotes static fights as opposed to the run and gun style that was essential in classic shooters- including games like the Dark Forces saga.
