Post here what you think is unrealistic about TPT and what can be changed. No flaming or anything, this is just for fun discussion. (I know most of these won't make it in the offical)
Nothing. It is real life that is unTPTistic.
The acid and caustic gas elements. While real acids do dissolve certain things, they only dissolve an amount of matter equal to the amount of acid, unlike TPT acid where a few drops will eat a huge hole in other elements.
Electrons and Neutrons do not make Hydrogen. This was kept in the game because it would break saves if taken out.
Speed of light is too slow.
