I've been playing FFXIV for 3 years now and have mained DRK since HW...I actually purchased HW because of DRK being my favorite class. I consider myself an decent to good tank but I always feel like I could be better. I pretty much do all content except but Savage content. Normal dungeons are a breeze but alliance raids can get a little hectic and sometimes confusing.

What are some general tips and advice that most people go by when tanking as far as positioning, cooldown usage and stance swapping. Also what are the best melds for a DRK? I'm currently stacking DH and SkS (for a 2.36 gCD) on the left side and all STR on the right.

Any other advice is appreciated as well.
