idea for adventuring fellow improvement

An idea to improve the fellow npcs, why not allow us to select what weaponskills the npc uses. such as at NPC lvl 68 I see no point in Tsuim using Slice or Dark Harvest when she has access to Guillotine or Spiral hell if i eat the quest food. At the moment there is a Rendevous Point option to tell the NPC not to use AOE weapon skills, so why not extend it further by being able to choose what skills to use for a given weapon such as :
Slice Yes No
Dark Harvest Yes No
Shadow of Death Yes No
Nightmare Scythe Yes No
Vorpal Scythe Yes No
Spinning Scythe Yes No
Guillotine Yes No
Spiral Hell Yes No
that way we can help customize the NOC to help us on solo weapon trial quest or just ensure the NPC is doing the max damage they can

For god's sake SE please omg add this please.

My NPC COULD be a huge powerful ally if it wasnt for the fact that she wastes half her weaponskills on gimp weak attacks that do little damage, when she COULD use weaponskills that I can create darkness skillchains off for sick cumulative damage!

Also, if you could add some kind of setting to make her less spammy on her enfeebling spells and focus solely on buffing me and curing me, thatd be great. It sucks when you have to constantly heal your npc because she drains all her MP casting crap like blind and dia on monsters that I kill in 5 seconds. It's because of this I just keep her on fierce attacker because her magic AI is just to wasteful with MP.

aye i forgot about the buff vs enfeeble ratio that would be a great addition
