Awesome. I really lol-ed at some posts... and I've encountered quite a few of these problems myself haha!
One thing though that stands out and really irritates me to no end is how companions seem to teleport/fall/wtf and take huge chunks of what I can only imagine is "fall damage" especially when coming down a hill. Sometimes all it takes is a pebble on the road and I suddenly hear the "ARGHHH" and then a gulp and a potion gone... lol
So I'm looking for the "stop dying while going down a fkn hill" skill, along with "a pebble on a flat road shouldn't do 90% damage to your health" passive... 
And omg the op's post with the pools of fire... hahaha... I simply gave up at the Hinterlands dragon and soloed him lol... the 3 other companions died exclusively because staying in the fire... lol
As for the commands... rofl... I imagine those commands (hold position, etc) as something of a suggestion. "Blackwall, can you stand over there and hold position please? Thank you"... 5 sec later Blackwall runs to fkville... *my character >
* ... haha!
