I do wish the bosses were instanced as you need a bit of luck to not have much respawn during a fight. It doesn't get much better either, the amount of crap that you can pull during the Yagluth fight........Bosses is something that could do with a lot of work, instance them and make the actual boss fight difficult, right now it is just : parry / attack, repeat until dead or if you can't be bothered parrying, just shoot with arrows, it's a bit of a joke.
