I think if they dont want open the zone back up a more reasonable way to cure the problem is to make it that evertime a grey attacks a red con player they become carnaged flagged for thirty minuets. This would allow the players that want to use the zone as intended and would make greys think twice before fame leaching.
PLus would allow the person that just got ganked by the leachers to get a lil payback.
Lets face it a group of 59 has a huge advantage over a lvl 70 especialy if that 70 is engaged in pvp with another 70. Greys have the chance to all gather around thier target and attack at once and now that lower lvl targets land more often you stay stunned or rooted whole time. Why they made it so lower lvl can hit you is beyound me. IMHO a payer 11 levels lowers should not be able to touch a lvl 70, yet twinked out 59's and thier groups do it all the time.
level locking guilds are just another avenue to get a stupid title that means nothing.
