Having finished my first (good) playthrough, this is my wishlist for future updates. The game was 10/10 for me until I encountered the first three things on my list which battered my perception of the game and I think need to be worked on. The rest of the list are things I'd like but can happily live without.
1)
A good ending where no one is turned into a mindflayer, makes the big sacrifice, or poor Orpheus has his brain eaten. We have Elminster visiting camp, the Wish spell exists in D&D and we are in loose contact with a couple of gods, surely we can do better than this.
2)
Give Karlach a "good" ending. So many good suggestions for better options in other treads.
3) Add an epilogue. What were the longer term outcomes of our choices?
4) The Upper City area fully realised. The city feels constrained.
5) An option to use the d20 system for initiative, using the d4 is far too predictable and boring.
6) Add more magic items, with a bent toward more variety (no need for more monk items).
7) Finish the bunch of the quests which were cut short.
8) Add an option to revert the duration and AoE of spells to the D&D5e standard.
9) Add more of the missing spells from D&D.
10) Add more classes and sub-classes.
11) Keep working on the Tactician mode.
12) Make the hotbar much wider for people with ultrawide monitors.
13) Allow Paladins to choose a deity.
14) Add Bane, Bhaal, Myrkul and Shar as deity options.
