This build takes heavy inspiration from the build showcased by Gypsy King, wherein he used Hunter skills, specifically IPS to Boost Rakk damage. I liked that approach, but it made me think about using Rakk Attack alongside mostly gunplay to constantly proc anointments and skills, specifically Power inside. Barring spending points into power inside and Fast and furryous, you will get on average around a 97% weapon damage boost as long as you are shooting and killing.
That's not taking into account a cosmic stalker com, which gives a passive 25% Hunter skill effect buff and can boost big game. If you are going to want anointed weapons for this build, be on the lookout for Weapon damage after action skill end, bonus elemental damage after action skill end, or a +100% damage on rakk attack victims anoint. Keep in mind, if you have a cosmic stalker com, you most likely will do enough damage to make not having anointed weapons an afterthought.
Skills of note that are for survivability are going to be your health regen skills, specifically Self Repairing System, Rage and Recover, and Spiderant regen, if you chose that particular pet and rakk healing.
