I propose that extra XP be given if you complete a slayer assignment. Just as with the agility course, this would promote actually doing the harder higher level assignment from the harder masters instead of going to burthorpe everytime. This would also make it more challenging then just killing some low level creatures all the time. XP given for completion of the slayer assignment should vary among the slayer masters and be something like, 500-1000xp for the master in Burthorpe and 2000-5000xp for the master in Lost City, etc. To me this seems like a logical addition. Thoughts?
