Im one of those people. And if i were lead designer i could have that issue fixed in a day. The most obvious first step would be to not make content that only half the playerbase gets to play, they shoudlve unlocked Qs on both islands for both factions. Giving us twiice the content.
Then theres mythic+, the most replayable content in the game, wich is gated to almost a month after launch.
Add to that, here are some more features that they could have had in the game at launch but choose to gate to several weeks-months later.
Warfronts, paragon rep, assaults, arenas, and raids.
Add to that, any chase items for any profession requires materials that can only drop in raids. So crafting professions are off the table aswell.
All of these features except possibly the invasions, are ready at launch, (we played it all on beta afterall). Yet are deliberatly gated, so its not a question of being unable to keep up with consumption. They are intentionally delaying content, releasing it in small bits to stretch out their MAU! Its not a conspiracy, its a sad fact.
