First I want to say that I don't think Mr. D and I are really on any opposite side an argument here. And team Helm isn't taking any offense.

AgreeMany more traps in the dungeons that players are likely to visit when they are /without/ a DM.
AgreeLocked doors of varying difficulty in those same monster lairs
AgreeChests with locks, you either bash them and probably lose whats in there or you take a lockpick with you
AgreeSecret doors
Agree .....with a caveat. Many tasks/statics could be done through use of various skillsets or differing approaches. I favor both specialized skill statics and statics *and* statics where different approaches can be taken to achieve success. (instead of just "kill the bugbear", charm him and convince him to leave, convince him to leave through diplomacy, sneak up on him while he's sleeping and coup-de-grac him, etc)statics that you can get only with the right skills
Agree. Although I don't think I am the mentioned "charisma-obsessed player from ages past" I have in the past and do now continue to advocate the incorporation of charisma based skills into many more situations. Nearly every interaction with an NPC could considered a chance to insert a charisma based check. I think I have done a good job myself of RPing my PC's poor CHA skills, trying to phrase things in such a way as to show the ineffectiveness in diplomacy of unyielding zealousness.social interactions and skills aren't really rewarded, you don't get to talk out more coins for doing the same haul in a longer time
I have a couple of years of ALFA NWN1 with a nearly entirely skill based PC. I understand the frustrations of having 12 ranks of bluff/persuade and only being asked to use it twice in game (thanks Darrenhfx and Damart

But I am also strongly alongside Rotku in his notion of not telling DMs how to DM. And the issue isn't really that the DMs don't know how. These are all smart people most of them with many years at tabletop and/or online with for the most part a good familiarity with the rulesset. But when we DM (I use the inclusive "we" to include my past life in ALFA and at the tabletop) there are times that rules get fudged. I have all confidence that current DM team does so in a manner that is meant primarily to improve the enjoyment of their players in the limited time they have to play. And that's the bottom line from my perspective.
