How to use Saw's L talent?

I got 2 coins, and it seems really interesting, but I don’t know how to optimize it. So you shank to get stacks and aa reduce your a’s cd, is it a wp or cp talent?

The shank drains energy tho, but i could see frequent shankings to improve mobility while also keeping stacks.

Also, should i upgrade it to lvl2?

Personally I like using it as CP SAW as a shank pew pew shank kinda thing (let’s be honest epic talents are all you see with WP)

Use it as CP saw…super hella fun like you can basically stab every single one of the enemy team…and about leveling it. I don’t really level up legendary talents(too expensive)

It improves shank damage by 15% so its decent, especially for cp. Thanks!
