We were playing the other night and it occured to me how much time people were taking planning their moves. I wonder if it might be a good idea and quite fun to impose a time limit? e.g. Your go to move a model, you have 45 seconds to complete the move.

It would make people think quicker and probably introduce more mistakes

Maybe also 30 seconds per model to decide what card it is going to use.

Might be worth a try?
