It sounds like you already know the solution to your problem.Also, let me clarify that my grind problem has been most prevalent with my group of 7 players. I don't experience it with my group of 4 (3 of whom play in my group of 7).
WotC's already addressed this a couple of times, both in official and less official capacities. I don't think there's really more that needs to be done. The solutions to the grind problem, if you have one, are pretty straightforward: don't run with more players than you can handle, make sure your players decide their actions ahead of time, roll attack and damage at the same time, and ensure that your players have all the info they need right in front of them. Power cards help. If none of this works, consider implementing a time limit on player turns.
