Hmm, in short to remedy the problem of not making the player feel like a hero would be to have that library I was talking about.
In there, you could view the records of people who have reached the hall of heroes or have been awarded some medal or something for beating the game. Also for any guilds that have ever achieved a top 10 ranking.
I would go so far as to say that statues should be erected for great players...but there are way too many.

Perhaps to remedy that stealth in tombs problem, as well as level compatibility issues from the new chapter, there would be a second, more massive tournament held in the new place, or whatever. You see, that way ANet could also eliminate complaints about no RvR. Some super massive 8 team battles, with NPCs are not more enemies than you would encounter in your average mission--so there probably wouldn't be any engine issues. That way, you could give assassins a fair chance, too.
