One addition. Don't blow up exploder shanks when they are next to teammates. There are some good ways to deal with them. Energy based attacks can disintegrate them without exploding. Fusion rifles are great for this as well as most charged melees. I've been running stoke the forge on my sunbreaker which recharges my melee on melee kills. It's a fantastic way of dealing with them and some other low tier enemies and makes for some good heals with cauterize.
