You know PvP was planned from the beginning, right? We knew Frontlines was coming before this game even had an alpha version... Is the game PvP-centric? No, sure, it's a story driven MMO, of course it isn't. Is PvP an afterthought though? IDK, interviews about what 3.0 was going to be (before we knew) and mention of Frontlines-style content back when I was fighting Nael Desu Darnus in 1.0 kind of give me the impression that they were thinking about PvP before they even decided on the theme/locations for 3.0.
No, you see more posts complaining about eye colour in the General Discussion section (which on a good day is a cesspool of inane threads anyway). You don't see many threads here about PvP because the PvP subsection is a thing. A thing the community reps seem to out right ignore, sure, but that is where the majority the PvP-centric comments go.
As for the devs not caring about it... Is that why Heavensward is going to have a new gameplay mode for Frontlines complete with new map? Is that why they (somewhat) recently added Slaughter to Frontlines? They care about providing PvP content, that much is obvious. It's also obvious that they're ignoring the real problems with PvP in favour of just pushing out more maps, much to my dismay.
The PvP teams resources (yes, they have a whole team dedicated to PvP, again, clearly they care about PvP) may be limited to make a simple adjustment to Wolves Den to allow 1v1 (lol?), but that is because they are wasting their resources on things like Slaughter and whatever horror 3.0 holds in store. This isn't like the plethora of Housing issues we have where they can just go "We'll the team was working on Gold Saucer", it's not a lack of resources, it's the misuse of them which is damaging PvP. Wolves Den was introduced very early on in this games life, and since then it has constantly been ignored, rather than fixed. Not really surprised Frontlines ended up suffering similar issues.
Instead of fixing those issues, they opt to make matters worse by further splitting the community with more game modes. I know they have fixes planned and glorious things like PvP Tournaments in store, having followed most of their interviews over the years, but it is always "after this Frontlines content". It's infuriating at this point...
