I'm using the normal sure footed because I don't have its primed version yet, it can be changed but at the cost of 1 more forma

Yeah, I'm using [Acceltra] because I prefer AoE damage, and in my view it's better than aiming head for head. If you are mastery higher than 12 I recommend [Zarr] Kuva

[Harrow] as hard as it seems to play is nothing like that, just use 3 first as much as you want (but always remember to leave enough energy for 2 and 1), then roll to be invulnerable and use 2 , and then quickly the 1, and done go out killing everyone and from there just restart the cooldowns. I almost forgot, when you are on top of several enemies use 4 and press esc (or the menu button you use) to cancel the animation.
