Yet it really hasn’t because it’s a gap closer not a controlled stun. Which is why it wasn’t put on the DR stun table till patch 4.0.6. However Charge remained off the DR table for Prot warriors because of warbringer talent. It’s literally fact and in any DR table and patch notes you want to look at.
I linked when Charge was put on the DR table and here are 2 sources there listing the entire history of Charge and the exact patch notes of when it was changed in these links. It’s very well documented and well yea, I have played with every iteration of charge.
