Related question: is anyone switching away from battlemats to theater of the mind for their 5e games? Or from something else to theater of the mind?
IRL, I know someone who's moving to theater of the mind for 5e.
We played TOM for our intro into 5E.
And it was fun and fine. We have some imaginative and creative folks. Loved it, felt very 1E. (granted we used minis for positioning in 1E).
But after a vote, they like the relative positioning, visual cues, and occasional diorama I create. And their minis!
So we use a battle mat, but we are still TOM, as some gray areas or technical details get glossed over (rough estimates, not much square counting)
