I've got the void damage ARMade short work of Axis Minotaurs and anything unshielded but really sucked against Shanks.
Marks are still capped at 100 per week so no reason to really throw them away for dismantling until you're near the cap.
If you do the daily story and complete a public event for the daily you'll already be 2/3 of your way through to the cap by the end of the week. Only really worth doing Strike Playlist if you're wanting loot or you need to cap out.
The harpies go down really quick with the Arc hand canon that can spawn in the vault. Max that thing out and it makes quick work of them ! 11 in the mag and the guy who was two manning the vault was using it.
