What is confirmed about dragon and some clarification:
1. On Todd being hunted by 3 dragons at one point and him telling to balance that thing: the problem here was that once he started fleeing from one dragon, he stumbled on more of them meaning: the problem was that there was a dragon every few meters away from one another. So what was changed was that
you won't meet a dragon every 5 meters, not that you won't have fights against multiple dragons (hell, I am pretty sure we will NEED to fight multiple dragons in later stages of MQ)
2. Dragons won't be neither new Cliff Racers nor new OB Gates. It has been confirmed that d
ragons have a chance of just ignoring you and won't attack you unless provoked. How often this will happen is unknown and I do have hope that Bethesda will find a good balance.
Also, there are dragons who know common language so you maybe we can even chat with some of them
3.
Dragons won't be level scaled in OB style. Not just because
OB level scaling has been kicked out but it has also been confirmed that
there will be more then one type of dragons and no doubt some dragons are stronger then others. Different types of dragons should take care of difficulty balance
4. It has been confirmed that
some areas are more dangerous then others. It is possible that dragons will appear in some areas more often (and be more dangerous) then in others
