I don't even play dragoon, but I've leveled it to 80 before the expansion and thought the class was fine. I know my limited experience with the class isn't enough to garner much weight to my words about it, but I have been in the same boat as you are now and it's unfortunate that others are in this situation. I think the class should stay as is. It is busy, but like you said it's not a bad thing. It made the class fun. SE needs to stop with this "this class is too busy" nonsense. I've watched 3 of my main classes get gutted the very next expansion (DRK, MNK, SMN) and it needs to stop. I used to play this game a lot, but since ShB when monk got gutted I stopped playing until 5.4 when they made monk changes. After the expansion dropped and it got gutted more I haven't been back since. I played AST as well and the class is fine. Best of luck to you and not having your class become absolute dogshit like other classes have.
