I'd like to see more traps.

Admittedly, I've yet to try the majority of the quests on the server, but the ones I have tried has sorley lacked traps, pickable locks or creatures that are not immune to Sneak Attack.
 
I'd really like to see more traps about and monsters who lock their chests with locks that are not Plot Marked. I am not just thinking about usual traps, but maybe some sort of levering system that would require a Disable Trap check not to drop i.e a fire bomb on the party, or locked doors that might enable the party to bypass nasty spawns.
 
If it's possible I'd also enjoy seeing more Listen, Spot or Search checks, perhaps the party would be able to see tracks pointing in the direction of the monsters they are hunting or the presences of other scouts/guerilla.

There are at least two quests that require a lock-picker to get the best reward chest, and four that are littered with traps. Sneak immunity was more of a problem for the quests in the city, where most enemies are undead or constructs, lefotvers of the Netherese. Try some outdoor quests. There are several popular ones with a wide level range with both sneakable enemies and traps to disarm.

If you're playing a char with two or more ranger levels, or I think 6 Druid levels, you can use the "/c track" command to track what's in the area. It's very handy in the wilds, and when you want to know what you're facing in a quest. More info is here:

That said, Jergali Crypt is a great example of how to balance things. A good mix of sneakable and sneak-immune creatures and some nasty traps that make Rogues useful. I would love to see more "optional" things like doors. Say, a side entrance to the Vrazdn keep that you can lockpick to flank the main room?

I second this.

There are even some quests where you practically /need/ a rogue to avoid a painful, painful (and frequent) string of deaths!
