Lets get this out of the way first: I am a lvl 11 Nord that does a little bit of everything (Destruction magic, archery, and typically one handed swords). I'm sure questions like this have been asked frequently on this site, and I have already read all of the answers. I know that arguably the best way to go is arrowing it until it grounds, then hacking at its flank when it is on the ground or continuing to arrow it while maintaining your cover. I agree with that completely. However, even with doing that I still stand no chance in hell against these things. Whenever I try to arrow it while it is flying, it flys over me and completely roasts me with firebreath. I tend to keep as many health potions on hand as I can, but I use almost all of them before I get the dragon to 3/4 health typically. I know most of you are going to read this and think "wow this guy sucks. I can 2 hit a dragon with a power strike." but I know that I am not the only one having these problems. So please, if you have any helpful tips on how to take down a dragon one on one, let me know.
