It sounds like you're more upset that you died than the fact that the GLA didn't know all his abilities. As others have pointed out, people can't learn how to play their classes if they aren't in parties, and quite frankly party play is a new thing in FFXIV world...at least exp party play. It sounds like the guy DID start using Provoke and other abilities when they were pointed out to him, so maybe you should cut him some slack. As others have pointed out, many different classes in game need skills from other classes to be 'at their best'.
Also, I liked your little dig that CNJ should know they're healers by now. You do realize more of their spells are DD magic spells right? Oh, and THM is the better tank/ exp party healer with Sacrifice. Add to that, believing that a GLA should automatically know skills they need to learn from other classes (which is unfair to expect in an exp party since they could be ranking a first class), maybe you're the one who needs to chill and learn a little more about party play.
Lastly, why did you not get a heal from the mage...and if they were healing you and that still didn't keep you alive and the mage didn't pull hate, you we're probably playing your job wrong. I mean come on, you died 4 times...maybe holding back a little on your damage while the tank got use to the party's play style might have helped too.
