So, I've been playing since 2014.
According to Steam I have 5056 hours logged in the game, probably 2/3 of which are "Active play" as opposed to things like opening the launcher and not logging in, which seems to tick up the Steam clock either way.
I have played pretty much every aspect of the game. I actively raided in Coils, crafted often in Heavensward, and in Stormblood I ended up becoming an FC leader. I've forged an ARR Relic and most of a HW one, till I couldn't be bothered to do another light grind.
Stormblood, especially where we are now, has nothing to keep me coming back, nothing to keep me playing. I only log in most of the time to update FC buffs, and do ventures. Most of my FC is the same. Even previously active members are logging in once a week. An issue is I've had this level of burnout on the game since the end of Heavensward on and off. Sometimes I log in to socialize, but I can realistically do that in any number of ways, particularly with Discord at my disposal.
The problem is, the content. There is just nothing here, to be frank. Every dungeon feels like every other. I actively look for the good in every patch, I TRY to get hyped up, only to find whatever new thing they are offering is just more of the same. I tried Eureka, and found it to be pretty awful.
The two dungeons that came out most recently aren't BAD, but they aren't engaging enough for me to run several times a week. I can't say I haven't gotten my money's worth out of the game. Even Stormblood was worth the price just for the expansion story alone.
I do not feel, though, that there is a compelling reason for me to be paying 15.00 a month right now, other then to keep my house. World PvP, true World Bosses (not 3 minute Faceroll hunts), more in-depth dungeons, random or Rougelike dungeons out in the world, things to really explore, not just VISIT. These all could be reasons to keep the Veteran player engaged.
There are lots of other ideas I have that could keep me coming back, and I am sure there are many others that could be suggest. What WON'T keep my interest is "2 Dungeons, a "raid" (either 8 or 24 man) and a Primal"" every patch.
I have healer, tank, and DPS jobs leveled to 70, and nothing is below 60 except Fisher, and I can't abide fishing. I try to do my part to find the fun in the game. The Devs need to do theirs to earn my continued payments.
