I am a DE wiz and my wife is a DE archer, we are looking for a good place to lvl after Fortress of Resistance.
We are hoping to find another good place that drops a decent bit of pots because, as you can see from our class, we have a lot of down time atm due to low mp.
Hopefully someone can direct us to a new/higher lvl spot with more 2x mobs and some mp pot drops.
The Warrior also has strong M Def... you could also try Bee Hive and use speed kills.
35-40 is really an ankward lvling time...I hate it more then a lvl wall really. Most of the time I lvl around Hardins Academy then, you can port there from Giran and just kill Grandis-Windsus-Fettered
One area that hasn't been mentioned is Field of Whispers/Silence around Heine.
I've just gone there as a DE wizard (lvl 33) and the XP is pretty sweet, plus with pots dropping like christmas down-time is almost a thing of the past (got 50% before having to rest, with no outside buffs/recharges or BtM). I'm not sure it would suit a Nuker/Archer duo though because most of the mobs are either 1x HP or 1/2HP so it would be overkill with 2 people, but its somewhere to consider.
ps. Watch out for the ranged mobs, they can easily take 1/4 - 1/2 my HP with 1 hit :p
the beehive has a quest from a girl emily i think that is on way to EG. get 100 honey run and talk to like 3-4 ppl in dion and you get a nice reward, i forget how much it rewards. lvl 34 quest
i'd suggest fields of silence also. you can get quest from heine to get some extra money and mats. really good exp and reward for the quest is also nice Quest (http://lineage2.stratics.com/content/library/quests/index.php?id=15016)
and i found the money drop a bit higher than other places also. one of the mobs is archery resist, but rest are just fine :)
