I don't know the EXACT names of TuanHA's routines, so I'll just call them "TuanHA Premium <class name>" for the ones I use. Sorry. Right now, I really only play my mage and warlock on a regular basis as I'm trying to get my legendary cloak and my warlock is my primary main. My mage is going to be my alternative main when I get tired of playing my warlock. Also, all my toons are PvE based. None of them PvP.
Druid:
Restoration (462 ilvl) - Leaves Premium by Mirabis
Feral Cat (??? ilvl) - Superbad 4.0 by handnavi

Retribution (??? ilvl) - TuanHA Premium Paladin
Mage:
Frost (498 ilvl) - Portal Premium by Millz
Rogue:

These are just the routines I use, personally. I can't say whether or not they're the BEST for any given situation, but I enjoy using them the most. I can't suggest any settings for them, either. I always tool around with them and change my options as I'm always trying to figure out what gives the best performance. I haven't found out what does yet. It's always a work in progress.
Edit: Since it's been a while that I've played my druid, I forgot that I use Leaves and not Oracle, lol. Thank you Frayman for reminding me that Leaves is my druid healing routine of choice. I also decided to throw up my off-specs too, with their routines. I really can't remember my OS ilvls because I rarely ever play my OS, so I'm sure my ilvl is really low, or I just use my main spec gear, which is bad, lol. I really need to dust off some of these toons and get them above 496 for SoO. Sheesh!
