Two things,
Overheads are pretty terrible after the turn nerf
However...
The person was chambering where the person was at the time, not trying to anticipate where they were going to be.
The turn rate nerf should just be removed (IMO), or only applied to the weapons it was meant to hurt (mauls/long pointy sticks). For mauls it wasn't so much that you could helicopter spin and hit anyone in your circumference, the problem was more that the maul would be at the swingers knees, or worse on the ground and you would still be able to count a hit on someone.
