Can the 4-8 limit people stop now, please?

Flex raiding was implemented just before WOD was released so just over a year ago.

And WoW is a 10+ year old game, so they've had around 9 years to implement 'flex raiding'. FFXIV hasn't been out even half of that time. People need to be patient and allow them to expand the game.
