SWTOR was honestly the most fun I have ever had, but that got cut short when my WoW raiding buddies quit that too. FF14 is very good, but it just doesn't quite have that staying power. The problem is that all these new-age games seem to be either too casual-friendly, or else azn grindfests + loot treadmill.
Not really leaving yourself much room there. Casual-friendly sounds like something that isn't even a bad thing, since streamlining processes is much easier than hand-crafting every item like you do in FF14. Unless you mean something other than what I'm thinking. And grinding is all people do in any MMO-style game to prevent themselves from appearing casual.
I play GW2 and enjoy it. It's a free game with two $30 expansions. You can jump and do other casual-based stuff, like roam solo and craft things you discover automatically. It has raids, dungeons, and fractals, which are like dungeons that increase in difficulty as you go higher. There's a good amount of end-game content. PVP and WVW are post-endgame when you're good enough to play against other people, and while the community is pretty cancerous you can usually find some decent people to play with. The main story + Living World S2 + Heart of Thorns + Living World S3 + Path of Fire + Living World S4 will run you at least 400 hours. It looks much better than WoW and is updated frequently. The only thing you wouldn't get to play story-wise is Living World S1, and I'd honestly buy it just to play it.
No furry nonsense, no bondage armor, and very few bikinis though, if that's something you do in RPGs.
Also, there are still monthly subs. SWTOR and FFXIV are both being worked on still. Having the option to pay a microtransaction fee for some shitty Mooby skin to support the devs isn't the same as paying just to play the game.
