TSW is running a free trial this weekend. It runs til 7am Monday 6th.
It's the one I'm playing atm. I hate the PvP but the PvE experience and atmosphere are unique. Some of the missions are downright creepy, even scary. It also just got its 1st monthly content update which added some new missions and nightmare-mode dungeons.
I think "immersive" is the word I'm looking for. If you use guides/walkthroughs and rush through it, it will suck. If you take your time to experience the world (which just happens to be my style) you will love it.
Combat can feel a bit shallow early on, because the deepest part of it is building your deck aka build. Or should I say deck
s since the more difficult content assumes that you'll be able to switch roles when needed. The builds in this seem pretty simple at first because you're limited to 7 active and 7 passive abilities at any one time. That seems really dumbed-down to those of us accustomed to 4+ action bars, but the variety is there. There are different types of attack that synergise with each other, there are mobility abilities (teleports, charges, dashes), purges, cleanses, group buffs, DoTs & debuffs, interrupts, direct heals, shields, HoTs, leech effects and some aggro abilities. I might have missed some.
So for example I have a DPS deck with some AE and roots for solo play, and swap in a couple of healing abilities for tougher solo fights or mobs that are immune to root effects. In groups/dungeons, I can swap out the AE abilities for bigger single-target nukes and a gropu damage buff, and I can swap in a cleanse and/or purge to help the healer out, or swap in some direct heals and swap a couple of damage talismans (ie. gear) for healing gear, and take the role of off-healer. That's where TSW's combat depth comes in.
When it comes to nightmare modes and the upcoming raid you can also plan your deck according to what other people in your group are building.
Ctrl+F my name in here and see if I can't change your mind

Might as well at least give the free trial a go while it lasts
Bad points:
- Certain combat animations are a bit wonky, personally I only have one ability whose animation doesn't match its activation time so it's not really an issue for me.
- The UI isn't great for healers, and the addons to change it aren't fully mature yet. They do work, they just need some polish to make them more user-friendly.
- The auction house is broken... but happily the "bazaar" addon fixes it.
- No raid yet - it's due at the end of August.
