Changing the zones back would provide a smaller area for PK to happen, which is probably a good thing with the current size of our playerbase. I'm all for giving the old zones a second chance.
Fm would be gone, Tv to fd would be changed fd to gap gap to blight. The zones back then were a lot better and the way the current fd is set up promotes pansy pk. It also takes too long to get to a place to fight one of the like 4 people who pk on the mud.
I haven't learned these new zones yet but it seems spread out a bit more which imo is good to even out moves and such. I would suggest giving it some time and i mean a good bit of time month easily before deciding. Then come back and check it again.
The new Fal Dara and the zone around it were pretty weak, I'm glad they got exchanged. The rest of the new zones are nice though.
One thing. Remove FD's locking northgate, maybe give trollocs some mob support in the area to replace the mobs that were taken out when the zones was changed. Putting bowl back would be excellent, then give us a couple mobs around Gap somewhere.
I think the zones are fine, but channelers need to be reimp'd or, in lieu of that, more abilities and/or changes to current abilities need to be introduced for all classes.
For example, disengage bash should be reintroduced imo.
