Eberron is a funny setting in my mind. It talks about being lower level in the npc factor; it stats that PC classes are rare and gifted. And then it talks about how special being a mid to high level pc is, and how you are someone to be taken seriously. But in my mind, that is not the case. This thread is an example of this. From what I've read so far, it feels to me that most people are more interested in squishing the PC's hopes instead of letting them play.
I don't know about the rest of you, but one of the aspects of D&D that appeals to me is playing the hero; you save the world, defeat evil, and marry the princess. Now, I realize that Eberron is more of a pulp, bad guys will win sometimes kind of setting. It sounds to me that all you are trying to do is keep the PC's tiny little ants at the mercy of all the big, bad, scary organizations. Maybe the PC's can't take any army out, but I tell you what, by the time you reach 10th level in Eberron, your characters should be something that is feared and respected, since the whole basis of the setting is about that sort of thing. I'm not saying that the PC's should be handed the world, I am saying that the PC's are, by their very nature, special, elite, and powerful, and they should be given their due.
I'm playing in an Eberron game nwo, and my character has just recently gained 10th level as well. So far, all the DM has stated is "a few people have heard of you." Sorry, but in a setting that claims that 10th level characters are very few, and PC's are exceptionsal, we should be getting more than a few. The 10th level mage in our party should be getting alot of respect has one of the most potent wizards known in Khorvaire. Instead, we get stuff like, the small town on the Breland border has heard of you, but that about it."
Sorry about the rant, but I feel that instead of saying "oh look, the PC's think they are cool, I better make them look sad now," you should be letting them bask in their glory, and give them the chance to actually be a world power. Sure, there are bigger fish out there, but there always are.
