As a stalker (yes i know i'm 10 lvl's lower than most heroes in here), I can't see me useing this zone much if ever there are just too many builds who can individually see through both Hide and Stealth combined, which completely negates the whole AT's strength.
Placate seems broken in this zone as an example i was fighting a stray blaster after i AS'd him i placated him (there were no other heroes about so no team buffs to minimise placate), after i AS'd he ran through 3 buffs BU/AIM and PB i did not attack him during this and merely SJ'd away he then shot me when i was about 30' away theres wasn't time for placate to have worn off or for him to have que'd his attack b4 i placated him.
I think even long term i will only take Heroes into the zone i have built and killed off most builds both hero and villan and i think that hero's will long term have a large advantage. My scrappers feel godlike in there and not all are 50. I think the other zones are far more balanced as if you are teamed and the team plays well you will all do well(both hero and villan) a mixed team is usually the way to go but as i mentioned earlier i cant see to many stalkers playing in a zone where they are visable which gives the heroes a greater freedom.
These are just my opinions b4 everyone jumps up and down on this post and i'm not looking for a flame war.
