Personally I would prefer some extra attack options unique to assault rifles, like the grenade launcher/shotgun addons that have been floating around as ideas.
But Flingshot would likely be much easier for the already really really busy devs to do.
Burst performs ok vs evade profs already I think.
On BS and certainly in NW, RRFE is much better since it doesn't need to be refreshed. We can't expect not to die, and it'd be much better not to leave our teammates without reflects when we do.
It's pretty easy to do, they just need to make the team verion of our reflect auras have a different stacking order to RRFE in the reflect line, and make RRFE stack higher than all of them.
This is the nano the hours-long pre nul aura (which is in a seperate nanoline to reflects) casts on you every 10 seconds (unless you're AMSed in which cast it fails because AMS stacks higher)

This is the nano it casts on all nearby team members every 120 seconds

They're seperate nanos. All that needs to happen is make RRFE stack higher than the team version of Pre-Nul. Currently RRFE has a stacking order of 260, and team prenul is 285 (TMS 1x is 300).
