No. They shouldn't. There's so much rampant CC amongst most of the jobs and their netcode is bad for what is required from it like registering something critical like Resilience. It's pathetic, because they could just automatically have Purify grant Resilience regardless of whether or not you removed a debuff (like Fetter Ward); and suddenly we don't have to gamble against the poor netcode to decide if we get to be immune to debuffs or not for the next 5 seconds.

With how fast people can die from getting dogpiled on by as little as 3 people or chain-stunned to death in Crystaline, I have a difficult time understanding why people think adding 6 more bodies will somehow make it more enjoyable. If you want the music or aesthetics, that's fine, but that will never actually fix their PvP modes' fundamental issues. So I think if it's not something they can easily add without pretending that it took them half an expansion's worth of time and resources to do, then it's probably not necessary.
