Title pretty much sums it up, any help is appreciated!

I would really like to see an improvement to the task system currently in the game. I really like how one can talk to a master after recieving a task and ask for a new one as there are a lot of trash tasks. What I'm hoping to see sometime soon is the addition of tasks to kill monsters that are already in the game. I am NOT asking for the slayer tower to be added, as that will require a very large amount of time and effort, but instead am asking that monsters, blue dragons for example, that are already in the game be added to the task list. Vannaka is in fact supposed to assign blue dragons in the actual game which is part of why I don't understand why this hasn't been added. Also, please increase the rate at which a player is assigned the better tasks like ogres, dragons, etc. and decrease the rate of the less appealling tasks. I don't understand why crocodiles for example are so frequently assigned when they haven't even been implemented yet. Same goes for Infernal Mages and Otherworldly Beings. I've talked to others in-game that agree with me. Thanks for reading!
