I'm glad they put in so many zones with lots of good quests to do. On the last set, the hand aug is the only reason I even went to Buried Sea. Was nice to get a bit of a bonus while working on it. Natimbi, Broodlands, and Bloodfields being the exception to the many quests in the zones. And I'm not really found of those three either, but Natimbi is ok. Way back when GoD was new, I used to fear kite the crags on the Ranger, until they started turning light blue back then, green it would be now, was descent solo exp while lfg.
Although Lavastorm is a low-level zone, hopefully it will help a bit with the DoN quests that end in the zone. There's a few a do quite often for faction on various toons.
Blightfire has tons of quests, although not too many of them great, still extra exp.
I still do quests in Firioni Vie from time to time.
Never really liked Gunthak, but the spell quests there are nice, and it's a popular 30s zone for leveling.
Barren Coast has lots of quests, several for the hand aug, but most of the killing is in other zones.
Arcstone has lots of great quests, and as said previously is way better than KT. I still wonder who came up with KT as an exp zone? Had they ever been in the zone, let alone tried to kill stuff there? Although I did get several meldstones while I was there looking to discover the hotzone aug, not likely I'll use them though, with defiant gear, why spend 10-20K on a piece of gear you'll only use for 10-20hrs of play.
It doesn't appear there are many quests in Elddar Forest, but I recall a few good aug drops there.
Loping has alot of good quests (mostly faction, but Vrald's bag is awesome xp, and a great bag), and will probably be one of my favorite hang outs, and maybe get the prices down on the LP attunable gear for new/returning players.
No clue on Blackburrow, unless it's the reinforced version again. It should be good, if so, but very few, if any worthwhile quests. Lots of great gear though, and some nice clicky drops.
Just my toughts, and I hope the servers come up early, so I can start searching for the hot zone augs, but they probably won't, and it'll be later tonight before I can back on. :-/
Yther Ore.
