So my main is Dragoon at the moment. I leveled up Marauder to 15 because I thought I needed it for Dragoon but it turns out I didn't. Just to kind of spice things up a little, I'm thinking I may continue with the Marauder and learn the way of the tank. Might help me see the bigger picture better to play in another role than DPS for a while.

I'm nervous about doing an actual dungeon though because I don't know what I'm doing. If it's something that can be put simply... what are some of the little things as tank of a group that I need to keep in mind? Stuff that when you're playing with a bad tank, you notice immediately? Maybe vent with some stories so I can learn what to do, and what NOT to do.

Also, are all tank classes/jobs built similarly? Will I be in over my head with Marauder (and whatever Marauder turns into) or should I start with something else?

Appreciate any insights!
