Hero skill trainers, none for my primary?

I started nightfall with my tyrian ranger. When I go to the hero skills trainer, I can't ever get skills for the Ranger profession. But when I go to the Hero Skills trainer with my elonian elementalist, I can teach them elementalist skills.

Is this a bug or is there a reason why there is a difference between elonians and tyrians?

well, if you learned the skill which the trainer offer, you can't see them
I guess your Tyrian ranger learned the elona skill before meet the hero skill trainer

There is no option when I speak to him for him to teach skills to the ranger profession. When he lists all the professions that I can choose from to see what skills are available, ranger isn't in the list.

Do you have a Ranger Hero?

And if you have already learned the Hero Skills that the Hero Skill Trainer gives to Rangers, they will already be unlocked on your account and available for your Ranger Heroes. Therefore the Hero Skill Trainer won't display the Ranger profession if he has none to offer.

Yes, I have a ranger, hero. That's really irrelevant as you can learn ritualist skills and there are no rit heroes and can learn paragon skills prior to having a paragon hero unlocked.

That may be the case that he doesn't show the ranger profession because I already have unlocked all the skills that he would teach me. I think it would be better to show the option for the ranger profession, but when you choose it, if there aren't any to just say there aren't.
