Top tree arc strider, melee is now on a base cooldown if 25ish sec so once str is applied is ~15s. Dodge for extended melee range, shotgun at 9m-10m & melee. If you really want to build into it, liars handshake. If you're max light, wear a 1320 cloak which will drop your light to 1328. You will then get bonus progress on anyone at 1330 for the cost of ~1%-2 dmg.
