Disagree as action points are so scarce, but I can see that doesn't seem to be a popular opinion...
I feel DND is an managing resources, especially during combat. In able to switch to two hander then change to shield on enemy turn with no cost diminished that.
I can understand that, but only if there are enough resources to manage. At the moment, one combat action and one other action per turn is a little... frugal. Especially with the very high chance to miss and even if you do hit to find you rolled "used strong language" instead of actually causing damage. I know some of it comes down to both tactics and experience with D&D, and I have none of either.
I agree with the OP but I know what you mean. I for one spam the shit out of being able to move things about the inventory(to my advantage). Also IIRC, there was a distance limit too for swapping items between characters.
It's very handy for selling stuff when on a looting spree: park one character next to a vendor and have the others
covet steal all the
precious things.
Must remember to use the phrase "spam the shit out of" more often.
