I would love for them to have a core rules difficulty option just like Baldur's Gate 1 & 2 did. Some of the homebrew rules Larian is using make no sense whatsoever. For example, twinned spell with chill touch requires the targets to be in a little circle rather than just designating two targets. Why? Twinned spell also doesn't allow for concentration, so if you use it with witch bolt it does the initial damage but not the subsequent activations. Shove is a bonus action which makes a lot of combats a game of two hand shove football for the high ground. Reactions are not as player friendly as they are at the table. These are little things, admittedly, but they add up to feel less and less like DnD.
Twinned spell certainly allows for concentration. It's the ~most useful aspect of the spell: that you can Twin spells like Haste. Witch Bolt would do damage to both targets on subsequent turns.
But yeah I agree with everything else you say. Larian implements multi-target spells weird/poorly; shove significantly affects gameplay; reactions are very limiting.
