Keep moving; hit target lock for towers/nests and circle around while holding the Fire Breath trigger/key down. Once you take out most of the opponents you will automatically return to the battle tower.
I practiced flying around in the first transformation sequence, where there are only a couple opponents, which helped me get my bearings faster upon getting the battle tower.
You should have one skill point that you can put into Dragon Spirit, and can fly away behind the battle tower and use it to heal or otherwise rest up. You can get a second dragon skill point if you explore the fjords before getting the tower.
On the Xbox, a burst of speed is triggered by the left shoulder button (which probably would have come in handy a couple times if I hadn't forgot about it, until I accidentally hit that button). On the PC this is done by right clicking.
