The dragon fight needs more room.

We have what feels like no room to run around with in this circle. The knockback attack is just "haha you're dead" and its really freaking annoying to deal with. Run through 100 stun arrows to die to that mechanic in the last 10% is so frustrating and a waste of time. I want to put down the game and not even go into the new content because of this dumb dragon. Also we have to upgrade the flame twice to get to the new area? What??
