Time-gating content in MMO's has always been nonsense. If you have it ready for release, release it.
This.

Stop expecting SE to delay their content just because your own raid groups are impatient to clear. Either you deal with it, or find another raid group willing to go at a pace you'd prefer. Don't punish everyone else just because you'd rather take it slower.

Please don't speak for Square Enix on their behalf, thanks.
The post I was responding to was doing the exact same thing, so uhh... go bother them instead, thanks.
