Anyways, the point is this: we have a title for skills already but it's only for elites. And getting 180, while still difficult, pales in comparison to the amount of time, money and devotion one would need to get every skill on one character.
So if one was to accomplish this, what would he get? Just the skill hunter title which doesn't show that he has all the other skills in addition to the elites.
So I thought, that accomplishing this task deserves it's own title.
And what would that title be? None other than...for example if you were a Ranger,
Getting all the skills for all classes: Grandmaster Ranger
You could of course replace Ranger with whatever the profession would be.
And the way it would work is this:
(Ranger as the example again)
Unlock all primary profession skills: Adept Ranger (1)
Unlocked 1 secondary profession: Advanced Ranger (2)
Unlocked 2 secondary professions: Expert Ranger (3)
Unlocked 3 secondary professions: Elite Ranger (4)
Unlocked 4 secondary professions: Deadly (5)
Unlocked 5 secondary professions: Renowned Ranger (6)
Unlocked 6 secondary professions: Illustrious Ranger (7)
Unlocked 7 secondary professions: Legendary Ranger (8)
Unlocked 8 secondary professions: Master Ranger (9)
Unlocked 9 secondary professions: Grandmaster Ranger (10)
There's an extra 2 professions for the Dervish and Paragon when they come out. And those names are just examples, I'm sure Anet could think of better (but I would prefer if they left in Grandmaster as the last rank. I just like how that sounds)

I think this title fits the criteria for a good title. It's hard to get, it's special, it's cool and shows that you're dedicated to only 1 class (Don't think it's possible to get 2 characters with this title. At least not any normal person).
