One of the main factors of a story, is that no character is perfect, and at some point they acknowledge their weakness and attempt to overcome them. (or die, or something >.>)
The point is, no one is truly fearless (despite common beleif, this should apply to paladins as well) No one is truly unconvincible if the person is persuasive enough.
I've noticed alot of people who choose to play seemingly (I say this because I'm not 100% sure) Fearless characters. They dont seem to fear anything, not even things that would make most people logically shit their pants. I've also noticed that people wont let their PCs be tricked more often by not, if they OOCly think or know it is a trick. That is not to say Nobody does this - I personally give Kudos in a tell to anyone who actually allows their PC to be tricked.
Another thing I've noticed, which really really bugs me. There is some people who are very stubborn, but it is -very- rare to find someone who cannot be convinced if you set your mind to it/are persuasive enough. But I see that more often than not, Most people dont want to variate from what they outlined in their original concept, and will not listen at all to persuasive arguments that would seriously change their character's outlook on an issue.
I'll give a painfully Obvious example.
The Scholar. Anyone who was actually around him would know he made some amazing arguements on the side of Pro-necromancy. But nobody Listened because they OOCly knew it was evil, according to their FR sources. His arguements and attempts at persuasion were some of the best I have ever seen, but for the most part, they were wasted words. Im not saying his enemies should've just conceded and said "OMG you're right, necromancy is cool!" - But it should've at least given them some form of doubt in their own beleifs, enough to question it more.
People, please Keep in mind a true sign of an awesome character is not how strong they are or how many quests they can smash, or even how many PVP kills they can get. A truly awesome character is one with very real weaknesses and flaws, exploitable by others in some way. The truly awesome events are almost always inspired by a characters weakness. When I DMed, I would always watch a PC for awhile first, trying to figure out what would affect them most ICly, What would challenge their Pc's mindset most. Would they crumble under the pressure, or work to overcome it? Those were my most memorable experiences as a DM - Always the most interesting events to run.
In short, please try to remember weakness is a important part of every concept. While it may make you die abit sooner, or possibly hinder your leveling (oh no!) - I can garantee the RP experience will be much more fun for you and others.
Stop making "Perfect PC's" please.
