A very valuable lesson learned during the beta is to not kill the mini mob spawns at Arkfall Crystals.
For example the Skitterlings. If you leave them alone they will go towards the crystal and create a weak spot which leads to a much quicker and easier destruction. The same can also be said for cleave mutants as they will place explosive barrels at the Arkfall which can then be blown up for quicker damage.
During the games full release at the new Arkfalls a similar trend should be found.
