I just don't understand how dragon armor being replaced by skilling supplies makes the Chaos Elemental any more popular. It's in the wilderness, for god's sake! Nobody is going to run out into the wilderness to get some logs as a loot...it still has the worst droptable out of any boss, with it's best drop maybe worth 3-4m. However, chaos elemental needs at least one powerful, or half-decent weapon or other rare drop to make it at least a little more popular. It's harder than the King Black Dragon, who is in a safe area, and has drops that far exceed the possible drops of the Chaos Elemental, and it even drops a pseudo-Dark bow.
The other updates are great, though.
