Larian Studios Forums Baldur's Gate III Baldur's Gate III - General Improve spellcasting (or skills) sequences

Obviously you never played this kind of games in MP or I´m not explaining myself the way I should.
Maybe you played XCoM2 or commandos2 in SP? They take simultaneous actions, you can shoot while the soldier is running, or throw a grenade when the others are executing his actions.
The animation pops up when a character is about to do something. If pops up when you are doing something, like throwing a grenade, It´s too late to do anything about it.

Usually knowing that another player is going to do something allows you to wait and see what he is doing so you do not disturb his action or harm your fellow party member with your skills or spells or put yourself in harms´ way. I do not know how else to explain that.
