Theres still alot of "fill in the blank" factors to be decided...but my orginal point remains solid.
As more people put a laser focus on speed secondaries and the speed gap closes in toward a 1 team speed meta.... (which is still a very very long way off btw) adding stun and retribution mods will increase the RNG factor once again making speed secondaries less important as peeps branch off from speed toward the new elements...
Of coarse there will be some that still focus solely on speed and will remain ahead of it all, but with the addition of additional RNG that number will be smaller than it is currently and buy devs more time for a better/permanent solution to black hole that is speed.
