Please leave Qeynos be.. It is already an amazingly well done zone... and does not need the fix-up like Freeport did. Not to mention Qeynos works perfectly fine as is and honestly Freeport was to until the NPC's pathing broke. Honestly, I'd like to see freeport turned back to normal (Doesn't even look like a evil city anymore..) and leave Qeynos alone. Just my two cents.
Merging the zones: good (hey, EQOA ran an entire no-zone world off a DVD.) Wiping out the neighborhoods: bad! I hated those instance-villages in Freeport.
