This may not be a "small" suggestion, but something that might be a little cool and add something to the game would be a sort of broader slayer task.
For example, having a chance to kill any dragon, wouldn't have to limit yourself to just black dragons, could switch it up and kill some Vorkath, KBD, or even just some green dragons in the wilderness.
You could expand a lot of slayer tasks with this, like demons, undead, animals, giants, and maybe even just a broad task of bosses.
Could make the slayer grind a little more fun even though it is already a top tier skill.
