NPC guide

I would love to have a better way of finding certain important NPCs. Such as, the NPCs who give Professsion Skills. It would be MUCH easier to gain more profession skills, if I could find the NPCs that gives them. This reminds me of Elder Scrolls III: Morrowind, where you were told where to go for quests. But, most of the time all you were told was along the lines of, "Take this trail to the East, and then go North to find a cave." Simple enough, but WHEN and WHERE should I go north? Do I take five steps East and then go North? Do I follow the trail until it dead ends and then I go North? It would be easy just to treat the profession NPCs as quests, but with no XP. That way we could all just follow the big arrow.

What? You can't find the skill trainer?

"Bob Saggit [Skills]" Usually lets me know what he sells.

Would you rather have:

"Bob Saggit [I sell, Monk, Necro, Warrior, Mesmer, Ranger, Elementalist, Ritualist, Assassin, Paragon and Dervish skills]?

There only a few important towns with respect to skills.
