I've been capped for about a week. I run a bunch of quests: BOB, tides, DA, VON6, etc.

Not sure what I'm supposed to be using my capstone for. Is there some clicky I should be using during these quests/raids?

Just seems like I am expected to pass out deadly weapons and then pew pew.
(note: the dps doesn't seem very good either, using GS bow and lucid dreams with kinetic maxxed out)
I did traps in VOD and a little kiting in bb in VON to get rid of excess eles.

Haven't figured out any purpose to the capstone.

Am I missing something?
