They have not added new cards and NPCs in every single patch. They added some with Heavensward, and tweaked a few NPCs. Still, they haven't added any new worthwhile content for the game.
- No new rules.
- no new tournaments in different areas, etc.
Also, what about Chocobo racing? There hasn't been a single update for that since it was released.
- Why are there no server leader boards, or new racing areas based-on the expansion zones?
- When are they going to fix the completely random way stats are distributed while breeding? Basing the stats off the grandparents, rather than the parents was an awful idea.
- Why can we still not trade cards/mating rights with friends?
- Why can't we queue for Chocobo racing outside that single room yet?
- When are the going to fix the random lag which causes item chests to not appear for players?
I did not completely dismiss PvP. warrior has reigned supreme in pvP for months, now. They're unstoppable. SE knows this, but rather than fixing it during one of their maintenance queues, they left them drastically overpowered. Will they be nerfed? Most assuredly. Does it look like SE's simply ignoring the problem? Yes.
There's also the riddle questline, which people loved.
No one said there's a lack of new content. People are complaining it's the same old, tired tredmill. if SE wasn't so keen on cometely invalidating people's work every few months they'd have time to expand the world and work on things players actually want to do.
Let me reiterate this because you don't seem to be grasping what I've said from the start of this conversation: It's not that SE fails to create content. They're failing to nurture the content they do have while tossing more unfinished ideas at us every few patches. People aren't upset because we're getting 0 content every patch. We're upset because SE isn't taking the time to fully realize the things we do have, and enjoy. My favorite parts of the game involve side quests and the gold saucer. Some people enjoy PvP; and that's okay, too. We all just want SE to really work on the aspects of the game we do enjoy instead of pushing it aside right after it's implemented.
There's nothing wrong with complaining. There's nothing wrong with saying, "I'm not happy with the way things are." Just like there's nothing wrong with being happy with the way things are. the people here don't have to articulate every tiny reason they're not happy and give detailed solutions to all of their grievances for said grievances to be real.
Just take the echo for instance. It was a huge plot device up until 2.2, where it became a generic, 'Primals can't enthrall you,' device. Why did we stop enterring people's pasts? Why did Moenbryda need to die when we could create spears of light to banish/destory Ascians without that device? We possessed the echo even without the crystals' powers. Even if that was the case and we did need the crystals, we never use it in the expansion, even though we've already collected a ton of them again. that's jsut one of many examples of SE having an interesting aspect to the game and completely dropping it for no apparent reason.
