Guild Wars 2

If you ask me, the scepter should be a hybrid damage weapon connected to confusion, at least fluff-wise. The problem is: confusion sucks (in PvE). One solution would be anet changing the mechanic to something %-based, increase the attackspeed of mobs, etc. Another way to make the scepter attractive (as a confusion-type weapon) could be something like this:

1.) Confusing Images
Cast an arc of energy to your foe. This attack will hits 9 times for a total of x damage, multiplied by y % per stack of confusion on your foe. At the end of the duration, Confusing Images will add one stack of confusion. You can cast other spells while casting this spell.

2.) Illusionary Counter
Block the next attack. Counter by applying torment and creating a clone that casts Confusing Images. If you did not block until the end of duration, you will create a clone casting Confusing Images.
2.a) Counterspell
Shoot out a blot that blinds and damages foes in a line, dealing more damage for each unique condition on targeted foe.

3.) Shattered Images
Cast an explosion of energy at your targets position with a radius of 300. Foes inside this radius will get 3 stack of bleeding and take x damage, multiplied by y % per stack of confusion on your foe. Allies inside the radius will get Aegis for 4 seconds. Shattered Images will remove all stacks of confusion on target foe.
