I completely agree that transmission is inferior to returning home with tons of science. Maybe transmission values are too low, however, I think the new store-everything-in-the-pod system may also be op. I like being able to store stuff in my pod, but a limit would be nice, so I couldn't do all the biomes on Minimus in a single seat pod. (you know kerbals don't sample pebbles, it's they return a sack of rocks that makes Santa jealous) If this was the case, you would seriously consider the 40% transmission rate on an interplanetary mission, and you would most certainly bring a lab if Squad was to add storage to it or something.
