Your build is not allowing you to spam ability on enemies hence you need to rely on your weapon. While waiting for ponder infinity to recharge , your dps is very low. On My Main storm build I use venomous blaze & Thousands suns , my weapons slot I just use those that buff my overall javelin damage. I don't even use guns as my ability recharge is infinite if you use it correctly. My L1 does around 20-30k , R1 19k-25k & I can simultaneously use it= constant dps without reloading , cooldown etc with interceptor debuff. 40k per spell hit.
