You aren't the only one. The only thing that the "fix" seemed to accomplish was more lag and combat with even more terrible bugs. I can't count how many times I did the electric slide using leap on my DK and teleported back and forth. I've actually felt bad for my opponents, and it does not feel good to win because the positioning and collision system is very buggy, even if it is not intended...

Do not get me started on combat in PvE...
