But dnc was from 5.0. But you make it sounds like dnc has be here since begin of Ffxiv XD.
Anyways what is the problem with 15y anyways when melee going to come to you anyway and at same time dnc is the only one with 4 charge of dash and best mobility compare to another range dps who all require target to perform.
Also to be fair FFXIV dev team never good pvp with all balance and server tick issue. So is actually good they try to change it with every expansion now.
