The greatest tank ever made in history is the UFS kin as you know. But now we need something thinner and smaller. In fact we need something really small that will hold at least 2,5 ml of liquid and it will not be a pain for achilles users. I wanted to make the best tank ever for all atomizers but its time for me to look after GG users first. So this tank will be very tiny, it will hold 2,5 ml of liquid, you will be able to put Achilles inside very easy without pushing it hard, easy reffiling, ability to expand in length, it will not rotate against Achilles, it will have clear window and one that doesnt brake under any kind of juice. Also with Achilles abilities for air and liquid control, I really believe that this combo will be the best by far tank system in the world. It will not have UFS's ability to adjust the liquid because liquid control is standard to Achilles, so no reason to make it like UFS
Its a different aproach to tanks and it will be really the best. Also its a rebuildable atomizer at the same time because Achilles will be inside.
If you think better, we will have an all in one system: Tank that takes all atomizers, very thin rebuildable atomizer inside that can go to other tanks too and liquid and air control build on the atomizer and not on the tank. I cant think of something better!!!
