A challenge for me is simply beating a game in the first place. This just gets in the way.
I dont really care about other people feeling good about walking over hot coals.
I did the same thing as you (except I didn't fight the dragon, I just missed the next fire) and felt really frustrated. The game isn't so bad once I realized they are pretty nice with the save point placement. Think of the respawing enemies as more of 'levels' that you must retry than an open world. That's what it's trying to mimic anyways from Demon Souls. You don't even have to fight the enemies most of the time. If you're quick, you can run past almost all the enemies between fires.
