I want a challenge, something most games lack these days. Hopefully we can tweak this through the console or a modder makes this happen.
I want a challenge to, but not an unfair one that puts me in a situation where there's no hope of succeeding through no fault of my own, and being chased by three dragons at once could be argued to be such a situation, at least I hope it is, because one dragon is supposed to be a challenge, if three dragons isn't a situation where you have no chance to win on your own, then Bethesda didn't do dragons well.
Edit: On-topic. As one of the first commenters said, It made the game designer feel an emotion, Why would you remove that?! It's obviously a great occurrence. Besides the OP makes a great point, Not every battle you face in life are you supposed to take head on. Sometimes it's just better to just run the hell away.
Feeling an emotion is only a good thing if that's an emotion you actually want to feel while playing the game. If the emotion a situation invokes in you is the desire to smash your computer, then that is not a sign of good game design. Games are supposed to be entertaining, not aggravating, and yes, facing impossible odds is aggravating, when I face a situation I can't succeed in, I don't think "This is terrifying.", because I'm too busy thinking "I hate this [censored] game and don't want to ever see it again!"
And what do you do if there's nowhere to run to? You can't exactly outrun something that flies easily, your only hope to avoid a dragon is by finding somewhere to hide where it can't catch you and wait until it decides to leave you alone, and what if it doesn't leave you alone? If the AI is like Oblivion, then we'll be having enemies chase us half way across the province, creating situations where the only option to run is only a good design choice if it's actually possible to run away from enemies. And don't say since the AI has been improved, that won't happen. You don't know that, no one who doesn't work at Bethesda could know that. You might assume that, but that doesn't make it true.
You may say being attacked by multiple dragons at once is a good thing now, but will you say the same if you actually encounter that situation in the game? We're talking about what's essentially throwing three bosses at you at the same time here. That's the sort of thing you'd rarely see in classic Nintendo games, it's certainly not something I'd expect to see in the Elder Scrolls, which has never been the most challenging game I've ever played.
