There is no balance in RPGs. Not in any real sense. Unlike something like a board game such as checkers, and RPG is just too complex, too complicated to ever be balanced in any real sense. And they don’t need to be.
You don’t need a fair chance to participate, all you really need is a chance. And you don’t need to have the same chance to do what another player is doing, all you need is the chance to do something; whatever that something is.
What it comes down to is, it’s your brains that give you a chance. You’ve got brains you’ll think of something. And it don’t have to work, as long as you try something.
Most importantly, is it entertaining? I got a balrog to kill a dragon because I entertained the DM. I tickled his fancy and he played along with it. Don’t approach the task with the attitude that you’ve got to win, approach it with the attitude that you could lose and your character will die—assuming of course that the DM is being merciful. Be humble, you can always gloat later.
Oh, it also helped that the other players were also amused, the DM was pretty much playing to them, and they all applauded my success in my prank.
So don’t fret about any crap like game balance or lies like that. Do something, anything, it just might work. And remember that there are many paths through a forest, some are just easier than others.
