I think on the contrary that reaction is what gives Larian the perfect reason to choose turn based over rtwp since the beginning and why they have to focus on and nailed it. 5e without a real reaction system removes a big part of strategy, and for me what would makes me quit. They are probably trying to make it more appealing over a simple pop up. Maybe something like ff7 Remake slow mo atb with a timer for example?
