You can fire off a lot of you arrows from out of sight around an obstacle. I tend to fire a flash arrow (slotted with hit debuff), duck round a corner and drop glue arrow, oil slick arrow, rain of arrows and then acid arrow (with fire and energy chance damage Proc IOs to ignite the oil slick)
Below level cap I would probably start a +1 difficulty with team size at 3 and then increase the team size to what I can safely handle. I like combat jumping on squishy characters so I don’t get immobilised.
A force feedback chance for +recharge IO in Explosive Arrow is great for getting powers back up quicker (ghetto hasten)
