The locked gate on Firesteep.

[Harlas Ravelkione]

As far as I know that gate has been overcome only a handful of times during the past 6 months or so, basically because no one can unlock it.

How about making it bashable, but making it either soak 10-15 danage pr. hit or giving it 1000 HPs? The epic trap will still kill anyone trying to bash it without having removed the trap, but it will allow a few more players to attempt to breach it and see what is hiding in there. If you are worried that spellcasters will easily be able to breach it with firepower, make it resistant to magic or invulnerable even.
With these changes people getting past the gate will still only be those who bring one who can remove the epic trap and/or unlock the gate. (which still not many can do, but a few more than previously)

I made it this way so that there was indeed something for rogues to ply their skill and to be wanted in a party.  There are a fair amount of these as well...though not enough probably.

Yeah, I think it should stay the way it is.

Key is able to unlock that door with a little bit of buffing. And I'm always on. If you can give her a good enough reason she will gladly help.

[Thunder Pants]

Lue is likely to be able to unlock it without buffs and while in combat, but i'm not sure what the DC is heh

It's good as it is. I've seen multi-
classed rogues handle the gate so it
is in no way too hard.
