For that matter, why require flags for progression to any zone at all?
With luclin, you were pretty sure, you could guage by the title how many aa that 60 has. If no title, you knew it was a weak 60, if class title, a stronger 60.
PoP gave us 65, and people went nuts on AA. Now there are SO many different 'qualities' of a lvl 65. You could get the "no aa, wearing fine plate, pl'd in 5 days" 65, or the "400 aa, time armor, knows their stuff' 65. Anybody thats gotten a tank in bot with 4500 hp knows the feeling of realizing that not all 65's are equal.
Flagging was a way to say "if they are in 'this' zone, they are at least 'this' good" Originally getting into PoV/PoS required the justice trial, and you knew that generally anybody in those zones had at least the capacity to complete the trial. Likewise, folks in BoT were good enough to do PoS giants.
With god, its the trials to enter KodTaz. I like the restriction, because it lets me know that those in the zone (generally) are good enough to play there.

) You and 72 of your best friends can take out almost anything (In fact when we took out the Rathe Council for the first time we had a few groups in a second raid).
