Is Keystone Master really supposed to be that easy?

Which I did.
I suggested the people in charge to pick melee DPS so they could benefit from Mystic Touch, which I would apply religiously to all enemy targets thanks to Zen Pulse, thereby maximizing the damage output of my group.
Insane plays by me. Just incredible.

You don’t fully understand it, but we are actually agreed.
I’m absolutely on board with you here. When it comes to difficulty, earning KSM is the same as reaching 1400 CR in PvP. Both goals can be reached with 4 buttons.

Let us shake hands, friend.
