So with a shared turn of party members that are next to each other in the turn order the combat got 10 times better, but there is still something missing.
If party members could delay their turn you could get all of your members to share one turn, which would bring much more strategic choise to combat.
As of right now you cant really come up with a strategy based on this shared turn idea because its just rng which members will be next to each other.
Also it makes generally a lot of sense to be able to delay ones turn.
Please add this feature since these combat rules really need any kind of variance to not get boring quickly
