Guild Wars is a very deep game. Reaching lvl 20 with my Ranger, ascending, acquiring the skills to copy and understand the synergies of builds from Wiki, tweaking them to taste, joining a good guild, finishing Prophecies, etc., etc., etc., I find that I have just scratched the surface. Just one example: I have seen one of my guildmates with heros, with such a synergistic combination of skills, gear, runes and secondaries (aggressive lions for everyone, lol) . . . . I am in awe, lol! And even Godlike Achilles, in Guild Wars, cannot go it alone. I believe Mastery must of necessity be highly adaptable to the situation: who is the enemy, who are your team mates, etc. But I readily admit that I know nothing. I humbly ask the Masters among you to outline a path, a syllabus, that those of us wandering in the wilderness (yea, though I wander through the Crystal Desert, . . . lol) can follow.

P.S.: PvP is a different animal; it deserves its own thread.
