It would be nice if moves like Sonic Break, Bow Shock, and Double Down did something else on top of what they do/will do. By that I mean those three abilities really only have one real use, to be used during your No Mercy Window, which is a little stale in my opinion. Mind you MOST abilities and skills exist to be used during burst windows, but I like when they add just a little extra flexibility or trait to them. Best examples I can give are like WAR's Inner Chaos and DRK's Shadowbringer that can have a charge held outside of a burst window to be used in at a specific time for 'X' reason that doesn't hurt their DPS too much as they don't have a self buff window like No Mercy. Or PLD's Confiteor spam that is a burst window that allows for ranged insta casting and will end in an AoE DoT. Or WAR's Primal Rend that functions much like Inner Chaos, but is a also a gap closer on the GCD.

Like, what if they made a trait that upgraded Sonic Break to make it a 25y ranged weaponskill akin to an insta cast Holy Spirit? Or made Double Down have increased range from 5y to 10-15y so you can have two GCD's in your NM window for easily moving a boss? Or make Bow Shock a ranged ability like Abyssal Drain? They could even do stuff that would only affect non-raid scenes. Like adding CC to any of them like how NIN's Doton applies Heavy, or how WHM's Holy Stuns.

Not trying to add any new buttons, but I think those three move specifically would feel more impactful if they did more than just damage in No Mercy every 60sec.
