I'm new to, FFXIV, but previously have tanked quite a bit of content in TOR. I'm not a particularly special tank, but I'm competent.

I'm struggling with enmity in early dungeons - I was able to take it at the beginning, but in a longer fight it was inevitable that I lost it. In each run I had a Summoner (I think) whose Carbuncle kept taking agro from at least one enemy, usually a completely different one to the one the other DPS and I were hitting. I don't know if this is just the player targeting the wrong thing, not having control or bad tanking - what do you think?

My rotation is fairly simple - lob, flash x2, savage combo. Mix in a flash every few combos to keep area agro and try to tab target where I feel i's safe, although if I do that I'd usually lose agro on the main mob I was taking. Has anyone got tips for early tanking? It's especially frustrating to not be able to get agro back if I lose it, even from a pet by hammering all my (apparently) high threat abilities.
