I know bloom isn’t on many weapons now, but it is on a few. In Reach, if you crouched, your accuracy would be a bit better. For example, in TU if you crouched with the DMR the bloom reset before you shot again. Stuff like that.
No OP. Crouching will not help you this time around. It worked with Bloom because of the mechanism setup, but here? There’s no need to beyond avoiding radar detection.
