@MikeQ The biggest trigger for me, I think, is I focus too much on showing people a good time and worry that I won't provide that. So then I go in to set up a fight with a giant that, while it has thematic tiers (like it drops to a knee at 2/3 health and gets more frantic, for example), turns out to not be a real threat to a party of four PCs. Getting the balance right is difficult for me without resorting to just cheesing them.
