I know this is a bit late, seeing as Dragon Slayer 2 came out almost a month ago now, but I didn't get into killing Vorkath until just yesterday, and after doing 16 kills so far, I love how much fun the fight is. It's not too intense, but not too casual either, just right in the middle. Reminds me of the GWD2 boss mechanics in RS3, which I also liked very much, so if the inspiration was taken from there, awesome. Average loot seems to be about the same level as well.
