1. Any resolutions on things you want to do?
Make battles more interesting.
2. What do you want to improve in your DMing?
Make battles more interesting. Not just harder, but more dynamic, descriptive, surprising, and play the enemy in a way that the party needs to work harder to support each other more.
3. Will you be trying out something new in 2019?
Using a horizontal display as a digital battlemap so I don't have to break the action drawing on a chessex battlemap or spend time and money printing battlemaps on a large-scale printer (or piecing together a number of letter sized portions of a map).
4. What are your DM weaknesses?
My players are so experienced it is hard to make battles challenging in an interesting way. I'm much better and creating puzzles, social encounters, skill challenges and the like. I'm trying to mix more of those INTO my battles. I'm also more comfortable having enemies gang up on a player, continuing to attack and unconscious character, and otherwise play unfair to force the party to have to spend actions on saving each other.
