What skill to enhance in Unity system? (Fire GS)

[MasterRoy]

When I first came back playing around a week ago, I've noticed there is this new Unity system which enhances stats quite a lot if used correctly.

My question is: what skill from Fire GS (now called Destruction path) do I have to enhance through Ascension stones? I'm pretty sure it is Carpet Bomb since Firefall is mostly used for landing Unloads and Sniper Stance is meh, but my opinion may be wrong, so I'm asking here.

Since it's mostly RNG which stone you get, start with whatever you get and keep working to improve it. Yes, Sniper Stance (like most ultimates) is the least useful. However, if you do get a purple or even orange-rarity one over a blue stone, stick with it until you can replace it.
