He was fine, missed a bit but by and large on the money. He booked the players that had to be booked and I don't know where people are seeing a "loss of control". Sometimes you just have to look at the players being a bunch of absolute whoppers.
Here's the thing with Burton (or any team who loses their heads and starts kicking). Everyone howling "You need to send one of them off to show a message" is all well and good, but if a referee only has yellow card challenges to punish (which they all were, in fairness) then you can't just flash a red to show a precedent...that's not how the system works.
What you can do is talk to and warn the captain/manager. And put it in your report.
