Yes, tried EVERY mount I have (19) and BOTH the purified demigod thoroughbred and the demigod thoroughbred are BOTH short approximately 1 second less in sprinting time than the other 17 mounts I have. The 2 mentioned above are approximately 3 seconds, all others are 4 seconds (tried them all to make sure). ALSO, the shattering animation of ALL barricades and surprise barricades that encircling you, is NOT happening on those 2 above mentioned mounts as well. BLIZZARD PLEASE CORRECT THESE ISSUES.
