Guild Wars 2

Since it would seem dual skills are supposed to be multi-click skills, why not apply it to all skills for a greater sense of control to make the thief class more about subtle planning and finesse.

Deathblossom-Press 3 consecutive times to apply all three bleeds. If you don’t press it 3 times before landing it won’t apply the bleeds that you didn’t click for. Because you know, being able to control how many bleeds you apply is useful.

Unload- Fairly straightforward, press for each bullet, first bullet consumes all initiative and shots thereafter consume none until you accidentally press it once more than the total 8 shots, then it consumes another 5 initiative.

Shadow Shot- Press once to shoot, press again to apply blind, press again to teleport.

Shadow strike- Press once to stab the person, once to torment and again to teleport back.

In all seriousness though, the only skill that I feel could actually benefit from the multiclick system would be flanking strike and that is assuming it is changed to do something extra should you decide not to steal a boon. Or at least make it like mesmer sword auto attack and do extra damage if there is no boon.
