3 is around because of drippers. Am I right? People? People? Am I right?
The issue is not really one of dripping vs a tank, IMO it's all about the power. More watts = more juice vaporized per second = more nic inhaled per drag. I have the feeling the Goliath rta will handle high enough power to give the high power drippers some competition in this department
But that's ok. If they're only vaping 3mg... more for the rest of us. 
apparently there is a big difference that's widely known.
