Richard,
this feature is very convenient on any controllers, for instance in cronus zen you can use any gun on the fly that has semi-automatic or automatic fire (before shooting in some guns you switch magazine to one bullet fire with D-pad) at a slight press on RT (1% to 99%), but when you fully press RT (100%) on the gun with automatic fire (before shooting in some guns you switch magazine to full auto with D-pad) you can shoot all bullets normally at once. The concept is that dynamic fire increases number of shooting bullets up to a certain point (in this case RT trigger press up to 99%), then full auto automatically switches on (in this case RT full trigger press or 100%). This feature saves so much time especially when playing PVP or PVE with dynamic scenes. In addition you don't have to switch between the macros every time you need rapid (or dynamic) fire vs. normal fire, you can use both type of guns (auto or semi-auto) or even pistol at the same time on the fly. I think if you want to stay competitive you should add this feature. Ghost Recon Wildlands, Division 2 are good games for testing this feature.
