Make 1.8 PvP work again

It would be great if 1.8 PvP (fast click) worked again. The entire PvP community is gone because of 1.9, but the few players remaining prefer staying at 1.8, even if it's been released in 2014. Actually, newer versions are only used for survival, all of the servers (just like Hypixel) support 1.8 and up only for PvP. Clients with 1.9+ have just more attack speed to compensate the differences with 1.8. Thank you for paying attention!
