How could or should the 6.5 mm Grendel be improved?

[VASCAR2]

With the way most Local government budgets are going I don't see any interest from Law Enforcement to transition away from 223/5.56. I know most Agencies are using various bonded core expanding ammo and I have seen no reports of failure to stop the bad guys. All the shootings by LE in my area using 5.56 patrol rifle/carbine have stopped hostilities with no additional rounds fired by suspect or required additional rounds from Officers. For LE use where suspects aren't wearing protective armor the 5.56 with the right ammo has been very effective in my area.
