No, the whole TES ethos, like todd said in the demo is be who you want to be and be free to do it.
I dont think they would force us to fight dragons if we dont want to play the MQ.. that would essentially cripple the sense of freedom and roleplaying.
I for one a looking forward to roleplaying a simple hermit who lives in the woods. I will pick herbs, cook food, chop wood and live a simple life. Cant really do this when a dragon is burning up my house.
You don't have to fight them. Run away.
The world does not and should not stop just because the player character doesn't want to be Dovahkiin. The dragons are still invading, they're still angry, they're still going to eat people. That's how I think it should be.
A quality roleplayer will allow his character to adapt to the events around him. Not demand they be changed to fit how he wants his character to be.
