Then why does the game arbitrarily limit content to pad its lifecycle to keep people subbed? Surely if the monthly fee is such a steal, then the content should be able to speak for itself. And if Yoshi P is fine with us taking a break when we are done with we want to do, shouldn't he just be fine with people finishing the content at their pace and unsubbing?
When 6.2 released with the savage tier for instance, I would've loved to unsub for a couple months once I was done with the content...However, I still needed to stay subbed because I needed to gear my main job and at least an alt job in the same role (just grabbing another weapon basically) in preparation for the ultimate that comes out in 6.3 which requires the best in slot gear. For me personally, this patch is great because the ultimate came out (though there were plenty of bugs this patch...), but last patch the game arbitrarily limited myself and other raiders to do a raid weekly in preparation to do the actual content we want to do later. those lockouts are still in place in this patch...
The concept of "do what you want and then unsub til later" doesn't work with this game. Housing demolition, Unreal trial rewards, Alliance raid, Savage tier, tome cap, etc. all are in place to keep you subbed despite the content. With all the flak Island Sanctuary got last patch, imagine if it also didn't give you any XP from gathering materials on your island. You could not control any of the pace at which you ranked up, and it was just a time-locked "here is your XP, come back later for more" content. It would've been even worse. Yet they allowed a very slow "grind" method that let people speed up the process if they wanted to put the time in, but was not required. Those that rarely gathered when ranking up got their XP at their pace, and those that had some more time on different days (or a lot of time) got to rank up at their pace. That is not how any of the weekly/daily/etc. content I mentioned above work.
