I kinda suggest toning down the Nalaeds. That "newish but not scumling" dungeon in Winterworth, mostly spiders and golbins. It has a cave/room at the end of it with 5 of them. Now, 21-22 acid damage spits when you're in Infernal and Full Plate isn't huge or anything, but 5 hitting you at once rapid fire spits that hardly ever miss. Well, most newbies aren't going to be in that so I checked out a plate and scale set, that's now 30 damage hits, from 5, all at once. Bye bye 150 health real quick, followed by another 150 two seconds later...so back off and heal, and get hit in the back by goblin fighters and shamans, all of a sudden that "easy" dungeon with easy to medium level mobs got tough. Not saying I'm pro or anything, but I'm pretty decent at the PvE. Definitely something you might want to look at for the "new player experience" moving up into dungeons.
Those Nalaeds guard the Neithial chest. I think they're about right for the level of difficulty because if the player has a neithial key they've probably been hitting harder mobs anyway. I don't think it's a room intended to be solo'd (even though you can definitely solo it).
