Better mod support is awesome. The problem for me is some of the most important things I still want in this game will probably not be solveable by mods.

- The Delay action. This was in D&D3, but in D&D5 its somehow missing. In the existing game, the very same combat gets orders of magnitude easier if by pure chance the game puts everyone in your group into the same spot in the initiative queue. Then "later" characters can act before "earlier" characters, i.e. everyone can freely coordinate their actions. If there are opponents in between the characters, thats not possible. In D&D3 you could reach this state intentionally with the Delay action. You just moved characters further down in the initiative queue until either you felt the need to act with them or until you had them all in one spot, thus you'd have reached the situation that you can coordinate their actions, and I dont get why its gone from D&D5 and I really want it back. By the way because of the strange way Larian implemented initiative, rolling 1d4 instead of 1d20, you can sort of "emulate" the Delay action by giving everyone the Alert feat and then they will often all be at the start of the queue.

- There are three spellcasting stats - the mental stats, Intelligence, Wisdom, and Charisma - and every spellcasting class uses one of these three stats for their spellcasting. However if you multiclass, then scrolls and items will use whatever spellcasting stat the last class you picked uses. Thats very random and often very bad. For example I would like to take 6 levels of Bard, then pick one level of Cleric, then return leveling the Bard. But that means scrolls and items now use the mediocre Wisdom stat, which is only 12 or 13, and not the Charisma stat which on a Bard you try to maximize. Obviously in P&P you can just decide what stat you want to use - well, there are further limitations in P&P, because there only some people can cast a certain spell from a scroll. Ideally one would just pick whatever stat is highest of those the character has.

- Better immediate feedback if you equip a character with an item they dont have the armor proficiency for. Always fun when you switch to a character in battle and they cant cast any spells because those great boots you equipped them are actually medium armor and the character lacks the proficiency. For example this item could be shown in red.
